Red-green color blindness (x ^ b) a recessive sex-linked trait. A colorblind male marries a normal color vision female.
Their daughter is colorblind.
What are the genotypes of both parents and the daughter for this trait, in words.
The mother is heterozygous, father is colorblind, daughter is homozygous.
Ob
Impossible to determine with the given information.
Oc
The mother is heterozygous, father is colorblind, daughter is heterozygous.
Od
The mother is homozygous, father is homozygous, daughter is heterozygous.

The correct answer is (a) The mother is heterozygous, father is colorblind, daughter is homozygous.
Since red-green color blindness is a recessive sex-linked trait, it is carried on the X chromosome. Males have one X chromosome and one Y chromosome, while females have two X chromosomes. In this scenario, the father is colorblind, which means he only has one X chromosome that carries the colorblind allele (XbY). The mother has normal color vision, which means she must have at least one normal allele (XBXb) on one of her X chromosomes.
The daughter inherited one X chromosome from each parent, which means she must have received the colorblind allele (Xb) from her father and the X chromosome carrying the colorblind allele (Xb) from her mother. As a result, the daughter is homozygous for the colorblind allele (XbXb).

I mean, both of us have the right answer it's just that you had it before me.

ok then explain it not just give it
toga:
or it will look like you stole it
IceSpice:
Why can't I just give the answer? It's great that you explained but for me I don't feel the need to explain.

Oh yeah, I gave a resource.

Heterozygous and Homozygous are words used to describe allele pairs. Individuals carrying two identical alleles (BB or bb) are known as homozygous. However, individual organisms bearing different alleles (Bb) are known as heterozygous.

what is heterozygous and homozygous ?
heterozygous refers to an individual having two different alleles for a particular gene, while homozygous refers to an individual having identical alleles for a particular gene.
Alleles are different versions of the same gene that determine specific traits, such as eye color or height. In a heterozygous individual, each allele represents a different version of the gene, which can result in a dominant and recessive trait. For example, if one allele codes for blue eyes and the other codes for brown eyes, the brown eye allele is dominant, and the individual will have brown eyes.
In a homozygous individual, both alleles are identical for a particular gene, and both will express the same trait. For example, if an individual has two copies of the brown eye allele, they will have brown eyes. Similarly, if an individual has two copies of the blue eye allele, they will have blue eyes.

@subshilava If you want it in simple terms:
Take "T" as a gene
Homozygous would be a person has two T's
So "T T"
Heterozygous would mean they are different
So something like "T t"
