The answer is determining hereditary diseases in individuals and families
This climate is warm.
The animals in the tundra are strong to live in such an environment.
I don't know what the rest of that stuff is sorry.
Answer:
20.3%
Explanation:
Given that:
An AAbb strain is crossed to an aaBB strain
i.e.
AAbb × aaBB
gametes Ab aB
For F₁
generation;
If the resulting progeny are now self-crossed.
We know that the genetic distance between these two genes on the same chromosome is said to be 10 cM.
i.e. the recombinant gene = 10%; Hence, the parental gene will be (100 - 10)% = 90%
Ab × aB = Aa AB ab Bb
From above; the parental gene;
Ab and aB = 90% with each being 45%
i.e. Ab = 45% and aB = 45%
while the recombinants genes are:
AB and ab = 10%
i.e. AB = 5% and ab = 5%
Finally; the percentage of aaBB is = aB% × aB% × 100%
the percentage of aaBB is = 0.45 × 0.45 × 100%
the percentage of aaBB is = 20.25% ≅ 20.3%
