Apea plant with round seeds (rr) is crossbred with another pea plant with wrinkled seeds (rr). what is the probability of offspring having wrinkled seeds? 0% 25% 50% 75%

The offspring must have one gene from each parent. To find the possible genes for all offspring, list all possible combinations that have a gene from each parent:

(Rr) | (rr)

R | r
R | r

r | r
r | r

The question asks for the probability of the offspring having rr genes. There are 2 offspring that have these genes out of the 4 created. Divide 2 by 4, then multiply by 100:



There is a 50% chance of the offspring having wrinkled seeds.

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
