This is a 2 factor cross punnett square-

An albino, nonhemophilic man, marries a normally pigmented, nonhemophilic woman whose father was hemophilic and whose mother was albino. What kind of children can they have and in what proportion? Hemophilia is a sex-linked trait.

how do bacteria ,protoceses , fungi , plants , and animals share the same characteristics ?

To determine the possible genotypes and phenotypes of their children, we can construct a Punnett square.

First, let's assign the letters "A" and "a" to represent the alleles for pigmentation, where "A" represents the dominant allele for normal pigmentation, and "a" represents the recessive allele for albinism. Similarly, we'll assign the letters "H" and "h" to represent the alleles for hemophilia, where "H" represents the dominant allele for nonhemophilia, and "h" represents the recessive allele for hemophilia.

Given the parental genotypes:
- The father is albino and nonhemophilic, so his genotype would be "aaHH".
- The mother's father was hemophilic (XhY) and her mother was albino (aa). So, the mother's genotype would be "AaHh" (one allele each from each parent).

Now, let's construct the Punnett square using the father's gametes (sperm) and the mother's gametes (eggs):

AaHh AaHh
----------------- -----------------
| | | | |
a H | a H | a H | a H |
| | | | |
-----------------------------------
| | | | |
a h | a h | a h | a h |
| | | | |
-----------------------------------
| | | | |
a H | a H | a H | a H |
| | | | |
-----------------------------------
| | | | |
a h | a h | a h | a h |
| | | | |

From this Punnett square, we can determine the possible genotypes and phenotypes of their children:

- Genotypic possibilities: AaHH, AaHh, aaHH, aaHh
- Phenotypic possibilities: Normal pigmentation/nonhemophilia (AaHH, AaHh), albino/nonhemophilia (aaHH, aaHh)

Now, let's look at the proportions of each possible genotype:

- Normal pigmentation/nonhemophilia (AaHH): 1/4 or 25%
- Normal pigmentation/hemophilia (AaHh): 1/4 or 25%
- Albino/nonhemophilia (aaHH): 1/4 or 25%
- Albino/hemophilia (aaHh): 1/4 or 25%

Therefore, their children can have normal pigmentation/nonhemophilia, normal pigmentation/hemophilia, albino/nonhemophilia, or albino/hemophilia. Each possibility has an equal chance of occurring, with a proportion of 25%.
