Answer:
The genotypes of the two parents: normal head shape (HH) and Bart head shape (hh)
The genotypes in the F1 generation= Hh
The phenotypes present in the F1 generation= All normal head shape
Explanation:
Let's assume that the allele "H" is responsible for the normal head shape while the allele "h" gives Bart head shape. According to the given information, both the parents are homozygous. The genotype of the parent with normal head shape would be "HH" while that of the one with Bart head shape would be "hh". Since the normal head shape is dominant, all the F1 hybrid progeny would exhibit "normal head shape".
Answer:
cause it's obvious that you dumb bruh lol
This is because of natural selection; since polar bears live in a rough environment, natural selection gives them more fur, more muscle, and can go longer without food
Explanation:
you just need to know that :
population density = no of ( what is asked) / land area.
