A gene encodes eye color. … If the child inherits two different alleles (heterozygous) then they will have brown eyes. For the child to have blue eyes they must be homozygous for the blue eye allele.Dec 18 2020

What are 3 examples of genotype?

Examples of Genotype:
  • Height. For an individual’s gene makeup there is tall variety (T) and there is short variety (s). T and s are called the alleles. …
  • Freckles or no freckles. Again the information that is passed from parent to child is carried in the cell of the genotype. …
  • Lactose intolerance.

What is a genotype and give an example?

An organism’s genotype is its specific combination of alleles for a given gene. So for example in the pea plants above the possible genotypes for the flower-color gene were red-red red-white and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).

What are 5 examples of phenotype?

In humans phenotype examples include earwax type height blood type eye color freckles and hair color. And phenotypes aren’t just physical traits. Behavior is also considered a phenotype.

What is an example of genotype and phenotype?

Eye color. The dominant genetic trait for eye color is brown which is represented by BB genotype. Thus in homozygous individuals the genotype for eye color will be BB or bb. … The phenotype of the individual that is the eye color in the individual is dependent on the resultant genotype for that character.

Is AA a genotype?

What is a Genotype? … There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA AS SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells. We all have a specific pair of these hemoglobin in our blood which we inherited from both parents.

Is being tall a genotype?

Genotypes can be heterozygous or homozygous. Phenotypes for plant height are tall or short. TT and Tt genotypes both expressed the tall phenotype because the T is dominant to t. Only the tt genotype expressed the short phenotype.

What is the AA genotype?

The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same i.e. both dominant or both recessive. In contrast the term “heterozygous” is used to describe the allelic pair “Aa”.

How do I know my genotype?

Sometimes a genetic test will give you your genotype. Sometimes you just need a bit of genetic luck in your family tree to figure it out. And sometimes you can tell the two genotypes apart just by looking at someone. An obvious way to figure out you genotype is to have a genetic test done.

Is BB a genotype or phenotype?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example this genotype is written Bb.

How do you write a genotype?

The genotype is often written as YY or yy for which each letter represents one of the two alleles in the genotype. The dominant allele is capitalized and the recessive allele is lower case.

What is the term genotype?

In a broad sense the term “genotype” refers to the genetic makeup of an organism in other words it describes an organism’s complete set of genes. … Each pair of alleles represents the genotype of a specific gene.

What’s phenotype and genotype?

A phenotype is an individual’s observable traits such as height eye color and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype while other traits are largely determined by environmental factors.

Which one is the best genotype?

Health Tips
  • Types of Genotype. The genotypes in humans are AA AS AC SS. They refer to the hemoglobin gene constituents on the red blood cells. …
  • Compatible genotypes for marriage are: AA marries an AA. That’s the best compatible. …
  • Solution. The only thing that can change the genotype is the bone marrow transplant (BMT).

What is a genotype of an individual?

A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. … The expression of the genotype contributes to the individual’s observable traits called the phenotype.

How do you write genotype and phenotype?

Can As marry as blood genotype?

However AS and AS should not marry because there is every chance of having a child with Sickle Cell Disease while AS and SS shouldn’t think of marrying. And definitely SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.

What is the genotype of a person with type O blood?


Someone with blood type O has neither the A nor the B allele. The genotype must be OO.

What is as genotype sickness?

Sickle cell trait (AS) usually does not cause any health problems. Often people don’t even know they have the trait. Sickle cell trait is found in 1 out of every 11 African Americans but it can occur in people of any race or background.

What are 2 examples of genotype?

Other examples of genotype include: Hair color. Height. Shoe size.

Genotype examples
  • A gene encodes eye color.
  • In this example the allele is either brown or blue with one inherited from the mother and the other inherited from the father.
  • The brown allele is dominant (B) and the blue allele is recessive (b).

What is a genotype example in humans?

Genotype can also refer to a gene or set of genes that leads to a single trait or disease. For example if your MC1R gene leads to you having red hair then you have the genotype for red hair. Humans are diploid organisms which means you have two copies of each chromosome—one from each parent.

Is being hairy dominant or recessive?

If you happen to be a hairy person you can guarantee that your children will also inherit this particularly fuzzy trait because it’s caused by a dominant gene.

Is genotype the same as blood group?

If someone has blood type A they must have at least one copy of the A allele but they could have two copies. Their genotype is either AA or AO. Similarly someone who is blood type B could have a genotype of either BB or BO.

Blood types and genotypes?
Blood type Possible genotypes

What genotype is FF?

Mendelian Genetics
Genotype Phenotype
F F Homozygous dominant No cystic fibrosis (Normal)
F f Heterozygous Carrier (has no symptoms but carries the recessive allele)
f f Homozygous recessive Cystic fibrosis (has symptoms)

What is the likeliness that the child will have wavy hair?

Wavy hair appears only in heterozygous individuals. … So the answer is that half of their children would be likely to have wavy hair.

What is the difference between BB and BB genotype?

The physical appearance of the genotype is called the phenotype. For example children with the genotypes ‘BB’ and ‘Bb’ have brown-eye phenotypes whereas a child with two blue-eye alleles and the genotype ‘bb’ has blue eyes and a blue-eye phenotype.

What is the genotype for a yellow plant?

The dominant seed color is yellow therefore the parental genotypes were YY for the plants with yellow seeds and yy for the plants with green seeds.

What is the genotype for white fish?

White is the recessive phenotype and it is produced by the homozygous recessive (aa) genotype.

What is phenotype example?

The term “phenotype” refers to the observable physical properties of an organism these include the organism’s appearance development and behavior. … Examples of phenotypes include height wing length and hair color.

What is a genotype in a Punnett square?

▪ Genotype: The letters that make up the individual. E.g. TT or Tt. ▪ Phenotype: The physical characteristics of the particular trait. E.g. Tall or short. ▪ Dominant trait: Signified by capital letter-E.g. T.

Can O+ have a baby with O?

That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. Each of their kids will also have a 3 in 8 chance of having A+ a 3 in 8 chance of being O+ and a 1 in 8 chance for being A-. An A+ parent and an O+ parent can definitely have an O- child.

What blood group is sickle cell?

The condition is often treated with regular blood transfusions so subtypes such as Ro are important in ensuring patients get blood which is most compatible with their blood type and subtype. Many people with sickle cell have the Ro subtype.

Which blood group can get married?

Blood type has no effect on your ability to have and maintain a happy healthy marriage. There are some concerns about blood type compatibility if you’re planning to have biological children with your partner but there are options during pregnancy that can help counteract these risks.

What is the genotype of the woman?

Using the definition of “genotype” that refers to a relevant section of the DNA sequence inherited by an organism the genotype of female humans is XX as opposed to male humans’ genotype XY.
