Answer: 25%
Explanation:
First find the trait that describes the pea shape because that’s what you’re being asked to find. In this case, pea shape is either wrinkled (s) or smooth (S). If the two plants that are crossed are both heterozygous, that means they each have one dominant allele and one recessive allele, which would like this: Ss. By putting both of the Ss genotypes (one Ss for one parent at the top of the board and the other Ss for the second parent down the side of the board) around the punnet square, you get: Ss x Ss= SS, Ss, Ss, ss. You are then asked to find the percent of wrinkles peas, which can only be shown when both alleles are recessive. By looking at the punnet square you can see that that only happens 1/4 times. When you turn that into a percent you get 25% of the plants that have wrinkled peas.

Nitrogen fixation.
Nitrogen fixing prokaryotes within the soil assimilate N2 to NH3.
Answer: Directional selection occurs when individuals with traits on one side of the mean in their population survive better or reproduce more than those on the other. ... Directional selection does the “heavy lifting” of evolution by tending to move the trait mean toward the optimum for the environment.
