Answer:
B. Black-eyed Susans and daisies used to be part of the same species. A random mutation in a subset of a population caused one group to release their pollen three weeks before the other, causing interbreeding to cease.
Explanation:
Temporal isolation, where temporal relates to time. So temporal isolation is the process where two populations will reproduce at different times/different seasons and therefore cause a split in species. In this case, we see the flowers release pollen at different times and caused a split into two distinct species.
Answer:
Body

Explanation:
Hello!
Yellow = Y
Green = y
Based on the fact that 25% of the offspring inherited two recessive alleles (we know this because in order for a recessive allele to be expressed, it must be homozygous),<u><em> the parent peas had to both be heterozygous. </em></u>
Yy * Yy will always result in:
1/4 = yy
2/4 = Yy
1/4 = YY
