Answer:
D) habitat isolation
Explanation:
Based on the information provided within the question it can be said that the main factor that keeps the two populations separate would be habitat isolation. This occurs when the different unique characteristics or preferences of the population's habitats prevent them from mating with those with different habitat preferences, thus maintaining them separate.
Answer:
a. only T gametes
b. only t gametes
c. TT
d. tt
Explanation:
This question involves a single gene coding for stem length in pea plant. The allele for tall stem length (T) is dominant to dwarf stem length (t).
- A purebred is an organism that will only transfer one type of phenotype to its offspring or produce only one type of GAMETE. Hence, to do this, a purebred must have a homzygous genotype. According to this question;
a. A purebred tall plant (TT) will produce only 'T' gametes.
b. A purebred dwarf plant (tt) will produce only 't' gametes.
c. The genotype of a purebred tall plant will be 'TT'
d. The genotype of a purebred dwarf plant will be 'tt'
