Let Y = yellow and y = green, and R = round and r = wrinkled. You cross YYRR peas with yyrr peas. All of the F1 individuals are yellow and round with a genotype of YyRr. You then perform an F2 cross and get the expected 9:3:3:1 phenotypic ratio. What proportion of the F2 plants are expected to be heterozygous for both traits?Multiple Choice1/161/49/161/2

A true-breeding pea plant with smooth green pods is crossed with a true-breeding plant with constricted yellow pods. The F1 offspring all have smooth green pods. If these F1 individuals are cross-fertilized, what proportion of the F2 offspring are expected to have smooth green pods?Multiple choice question.3/41/49/163/161/2

When a true-breeding pea plant that produces yellow round seeds (YYRR) is crossed with a true-breeding pea plant that produces green wrinkled seeds (yyrr), all of the F1 offspring produce yellow round seeds.  What fraction of the offspring of a F1 X F1 cross is predicted to produce green round seeds?  Group of answer choices

Two pea plants are crossed. 50% percent of the offspring have seeds with a wrinkled appearance (caused by the presence of a homozygous recessive gene). What were the genotypes of the parents?Group of answer choicesRR x rrRr x rrRr x RrRR x Rr

Round seeds (R) are dominant to wrinkled seeds (r), and yellow seeds (Y) are dominant to green seeds (y). What is the expected phenotypic ratio of a cross between an RrYy and an rryy individual?9:3:3:13:11:2:11:1:1:1

Now, consider a brown colored maize plant is crossed with another maize plant producing the following offspring [Green color is dominant over brown color; follows Mendelian inheritance pattern] If these maize plants are crossed among themselves, what is the expected genotypic ratio of the offsprings? 3:1 1:1 1:2:1 1:1:1:1
