what would the genotype and phenotype ratios be for a mother who carry's hemophilia and a father who is normals child?

Hh x HH

one half will be carriers.

Suppose you have monohybrid snapdragons in your garden and you find that they produce red seeds to white seeds in the ratio of 3:1. If the alleles are designated R (red seeds) and r (white seeds), what are the probable phenotypes of the parents (P1)?

i think its 7.....yep definatley 7 xD

To determine the genotype and phenotype ratios for a mother who carries hemophilia and a father who is normal, we need to understand the inheritance pattern of hemophilia. Hemophilia is an X-linked recessive disorder, which means it is located on the X chromosome.

Let's use the following abbreviations:
- XH: Normal X chromosome (non-carrier)
- Xh: Hemophilia X chromosome (carrier)
- Y: Y chromosome (from the father)

Since the father is normal and does not carry the hemophilia gene, he would have the genotype XY.

The mother, who is a carrier of hemophilia, would have the genotype XhXH. Even though she carries the hemophilia gene, she does not express the disorder because it is recessive.

Now, let's consider the possible genotypes and phenotypes of their children:

1. Sons:
- 50% chance of inheriting the normal X chromosome (XH) from the mother and the Y chromosome from the father, resulting in the genotype XHY, which is unaffected by hemophilia.
- 50% chance of inheriting the hemophilia X chromosome (Xh) from the mother and the Y chromosome from the father, resulting in the genotype XhY, which would have hemophilia.

Therefore, all sons born to this couple will either be unaffected (non-carriers) or will have hemophilia.

2. Daughters:
- 50% chance of inheriting the normal X chromosome (XH) from the mother and the X chromosome (XH) from the father, resulting in the genotype XHXH, which is unaffected by hemophilia. These daughters will be carriers like their mother.
- 50% chance of inheriting the hemophilia X chromosome (Xh) from the mother and the X chromosome (XH) from the father, resulting in the genotype XhXH. These daughters will be carriers like their mother but unaffected by hemophilia.
- There is no chance of inheriting the hemophilia X chromosome (Xh) from the father since he does not carry the gene.

Therefore, half of the daughters will be carriers for hemophilia, but they will not have the disorder themselves.

In summary, the genotype and phenotype ratios would be:
- Sons: 50% unaffected (non-carriers), 50% with hemophilia
- Daughters: 50% unaffected carriers, 50% unaffected non-carriers

It's important to note that these ratios represent the statistical probabilities and actual outcomes may vary. Genetic counseling should be sought for a more accurate assessment of individual risks.
