What is the genotype of a blue eyed woman?

What are the genotypes for blue eyes?

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. … In the eye color example, this genotype is written bb. Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.

What is the genotype of the female?

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.

Are blue eyes homozygous or heterozygous?

Being homozygous for a particular gene means you inherited two identical versions. It’s the opposite of a heterozygous genotype, where the alleles are different. People who have recessive traits, like blue eyes or red hair, are always homozygous for that gene.

Are blue eyes dominant or recessive?

Blue will always be recessive. If both parents have a blue allele, it is likely that the child will have blue eyes. However, if one parent has green eyes and the other blue, your child will most likely have green eyes, as green is dominant over blue.

What is my genotype?

In a nutshell: your genotype is your complete heritable genetic identity; the sum total of genes transmitted from parent to offspring. 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.

What is the genotype for a color blind female?

Females that are X+X+ or X+Xc have normal color vision, while XcXc females are colorblind. Males that are X+Y have normal color vision, while XcY males are colorblind. To determine the inheritance of red-green colorblindness (or any other X-linked trait), the genotypes of the parents must be considered.

What are the 3 types of genotypes?

There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.

What is the genotype of a brown eyed woman who has a blue eyed child?

If B is the allele for brown eyes and b is blue, the genotype of the blue-eyed man is bb. His wife must be a Bb heterozygote–she must have a B allele (she has brown eyes), but she must also have inherited a b allele from her blue-eyed mother (whose genotype was bb).
