Trenches are formed by subduction, which is a process when two or more of Earth's tectonic plates meet and the older, heavier plate is pushed beneath the lighter plate deep beneath the mantle, causing the seafloor and outermost crust to bend and form a steep, v-shaped depression.

What is the probability that the offspring will have purple flowers?; What is the phenotypic ratio for the purple flowers?; What
Luda [366]

The probability that the offspring will have purple flowers is 50% chance Let's go ahead and assume that:

The allele A corresponds to the color of flowers.

As a result, A would stand in for the alternate white hue and represent the dominating purple color.

According to the aforementioned hypotheses, a white flower would have the genotype aa while a heterozygous purple blossom would have the genotype Aa.

Now let's connect the two flowers:

Aa x aa

Aa Aa aa aa

The genotypes, phenotypes, and odds of the offspring would be as follows based on the cross's outcomes:

Purple color, Aa; 1/2

white flower color, aa, 1/2

In other words, there is a 50% chance that the cross will result in offspring with the flower colors purple (genotype, Aa) and white (genotype, aa).
