Apea plant that has round seeds has the genotype rr. it is crossed with a pea plant that has wrinkled seeds and the genotype rr. what is the probability that the offspring will have wrinkled seeds? 0 percent 25 percent 50 percent 75 percent

The probability of offspring having wrinkled seeds is 50 percent.

Explanation-

Round seed phenotype is a dominant trait over wrinkled seeds, which is a recessive trait.

Genotypes of pea plant with round and wrinkled seeds are given, which are Rr and rr respectively.

When Rr is crossed with rr, two genotypes ( Rr and rr) and two phenotypes ( round and wrinkled seeds) are obtained.

From the punnett square, the probability of offspring with wrinkled seeds (rr) -

= 2/4 = 1/2

Thus, 50% offspring will have wrinkled seeds.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
