Answer:
c. electron transport chain and oxidative phosphorylation
Explanation:
Here we would be using Hardy Weinberg equation for the calculation of allele and genotypic frequencies.
Dwarf genotype frequency =
= 25% = 0.25
Frequency of allele t = q =
=
= 0.5
According to the equation,
p + q = 1
p = 1 - 0.5 = 0.5
Now, the frequency of heterozygous tall plants would be-
2pq = 2 * 0.5 * 0.5 = 0.5 or <u>50% heterozygous tall plants</u>.
Answer:
The correct answer is option (D) there was a time in Pennsylvania history when dinosaur existed.
