Which of the following options is correct? It was important that Mendel examined not just the F1 generation in his breeding experiments, but the F2 generation as well, because
a) he obtained very few F1 progeny, making statistical analysis difficult.
b) parental traits that were not observed in the F1 reappeared in the F2.
c) analysis of the F1 progeny would have allowed him to discover the law of segregation, but not the law of independent assortment.
d) the dominant phenotypes were visible in the F2 generation, but not in the F1

b

Explanation:

It was important that Mendel did not limit his study to just the F1 generation because parental traits that were not observed in the F1 reappeared in the F2.

For example, in across involving a true-breeding yellow seedcoat pea plant and a true-breeding green seedcoat pea plant, all the F1 offspring would be yellow provided that the yellow seedcoat is dominant over the green seedcoat. The green seedcoat trait will only reappear in F2 offspring.

If the breeding experiment is limited to just the F1 generation, of course, the parental green seedcoat trait will not surface at all.

The correct option is b.

this process is called "phosphorylation." a phosphate bond joins adenosine diphosphate to form adenosine triphosphate.

i know can you plzz me with this question im sorry i didt answer your question i just need hel.
