One of Mendel's most significant results was the conclusion that genes determining different character- istics are transmitted independently. In pea plants, Mendel found that round peas are a dominant trait over wrinkled peas. Mendel crossbred a group of (rr, yy) peas with a group of (ww, gg) peas. In this notation, rr denotes a pea with two "round" genes and ww denotes a pea with two "wrinkled" genes. The first generation were either (rw, yg), (rw, gy), (wr, yg), or (wr, gy). plants with both hybrid shape and hybrid color. Breeding among the first generation yielded second-generation plants in which genes for each characteristics were equally likely to be either dominant or recessive. What is the probability of the event Y that a second-generation pea plant has yellow seeds? What is the probability of the event R that a second-generation plant has round peas? Are R and Y independent events? How many visibly different kinds of pea plants would Mendel observe in the second generation? What are the probabilities of each of these kinds?

Question
Transcribed Image Text:(b) One of Mendel's most significant results was the conclusion that genes determining different character-
istics are transmitted independently. In pea plants, Mendel found that round peas are a dominant trait
over wrinkled peas. Mendel crossbred a group of (rr, yy) peas with a group of (ww, gg) peas. In this
notation, rr denotes a pea with two "round" genes and ww denotes a pea with two "wrinkled" genes.
The first generation were either (rw, yg), (rw, gy), (wr, yg), or (wr, gy). plants with both hybrid shape
and hybrid color. Breeding among the first generation yielded second-generation plants in which genes
for each characteristics were equally likely to be either dominant or recessive. What is the probability
of the event Y that a second-generation pea plant has yellow seeds? What is the probability of the
event R that a second-generation plant has round peas? Are R and Y independent events? How many
visibly different kinds of pea plants would Mendel observe in the second generation? What are the
probabilities of each of these kinds?
