The substance is called DNA.
Answer:
C) 91%
Explanation:
First,
Express the Dominant phenotype as homozygous dominant(BB) and heterozygous(Bb).
Based on hardy-Weinberg equilibrium,
homozygous dominant (BB) Brown eye individuals will have the following percentage
B × B
(Where B = 70%)
70% × 70%
= 49%
heterozygous dominant (Bb) Brown eye individuals will have the following percentage
Using 2 × B × b (where B =70% and b = 30%)
2 × 70% × 30%
= 42%
The proportion of the subsequent generation with brown eyes
(homozygous dominant, BB + heterozygous dominant, Bb)
= 49% + 42%
= 91%
Mutation is the correct answer.
Answer:
b interphase
Explanation:
interphase is the resting phase when cells are not dividing
