What kinds of traits do not evolve through natural selection?
Harrizon [31]

Natural selection doesn't favor traits that are somehow inherently superior. Instead, it favors traits that are beneficial (that is, help an organism survive and reproduce more effectively than its peers) in a specific environment. Traits that are helpful in one environment might actually be harmful in another.

In pea plants purple flowers are dominant to white flowers.
algol13

Answer:

100%

Explanation:

This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (P) are dominant to white flowers (p). This means that purple color will be expressed in a heterozygous state.

According to this question, If two white flowered plants are cross i.e. pp × pp, the following gametes will be produced by each of the parent: p and p. Using these gametes in a punnet square (see attached image), ALL (100%) of the offsprings will be white colored (pp).

Therefore, 100% of the offsprings will be white flowered.
