Answer: Adaptation
species adapt to their environment
Answer:
Phenylketonuria, Cystic Fibrosis and Sickle Cell Anemia, these all are disorders caused by hereditary mutation.
Hope it helps!
Assuming the white phenotype is recessive. white: gg
I think the gray mouse is Gg because the offspring were pretty equally distributed in terms of color. See the punnet square below.
g g
G| Gg Gg
g| gg gg
If the Gray phenotype is recessive, then gray: ww but only if white is Ww because its about 50% chance for both.
Since hemophilia is an X-linked recessive disorder, the probability depends on the X alleles.
So, if father has dominant allele (H), the probability that a <span>female child would suffer from hemophilia (genotype: hh) is 0%, no matter of mother's genotype:
Father Mother
Parents: H x Hh
Daughter: HH or Hh
</span> Father Mother
Parents: H x HH
<span>Daughter: HH
</span>
Father Mother
Parents: H x hh
<span>Daughter: Hh or Hh
</span>
But, if the father has recessive allele, the probability that a <span>female child would suffer from hemophilia (genotype: hh) will depend on mother's genotype.
If mother is dominant homozygous, there will be 0% of possibility:
</span> Father Mother
Parents: h x HH
<span>Daughter: Hh
</span>
If mother is recessive homozygous, the possibility is 100%:
Father Mother
Parents: h x hh
<span>Daughter: hh
</span>
If mother is heterozygous, the possibility is 50%:
Father Mother
Parents: h x Hh
<span>Daughter: Hh or hh</span>
