The answer is C) 3/4
Let's analyze separately each of the traits:
Parental generation: AA x Aa
F1 generation: AA AA Aa Aa
So, all progeny will <span>phenotypically resemble the first parent.
</span>Parental generation: BB x bb
F1 generation: Bb Bb Bb Bb
So, all progeny will <span>phenotypically resemble the first parent.
</span>
Parental generation: Cc x Cc
<span>F1 generation: CC Cc Cc cc
</span>Only 3 (CC, Cc, Cc) out of 4 progeny will <span>phenotypically resemble the first parent.
The genotypes for first two traits will not affect </span>phenotypical resemblance to the first parent. So, it only counts the third trait, for which the chance to have progeny that <span>phenotypically resemble the first parent is 3/4.</span>
a) precipitation is balanced by evaporation
Before - question, research, hypothesis, experiment, conclusions
<span>Photochemical smog, created by the chemical reaction between sunlight, nitrogen oxides and volatile organic compounds is (e) generally worse during the winter months in part because of the increase in energy used to heat homes and other buildings.</span>
