Need the answer to 3 question's i am giving 30 points and brainliest for right answer. the gene for earlobe has two alleles; detached (a) and attached (a). what is the percent probability that one child of a mother with the genotype aa and a father with the genotype aa will have attached earlobes? use a punnett square to figure out the likelihood. a) 0% b) 25% c) 50% d) 75% the gene for pea shape has two alleles: round (r) and wrinkled (r). if a punnett square were used to genetically cross two parents with wrinkled peas, which genotype should be written in the lower-right square? a) rr b) rr c) rr the gene for earlobe shape has two alleles; detached (a) and attached (a). what is the percent probability that one child of a mother with the genotype aa and a father with the genotype aa will have the genotype aa? use a punnett square to figure out the likelihood. a) 0% b) 25% c) 50% d) 75%

Twin boys have girlfriends one of the couples have a baby would the dna of the lil baby be the same as the couples dna bc the boys are identical twins

To answer this question, researchers studied populations of the dusky salamander (desmognathus ochrophaeus) living on different mountain ranges in the southern appalachian mountains. the researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. four mating combinations were tested for each pair of populations (a and b)—two within the same population (female a with male a and female b with male b) and two between populations (female a with male b and female b with male a). the proportion of successful matings for each mating combination was measured. for example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). the reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (aa + bb) minus the sum of the proportion of successful matings of each type between populations (ab + ba). the table provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.
