You cross a pure breeding plantwith yellow wrinkled seeds to a pure breeding plant with green round seeds to generate F1s.

In pea plants yellow seed color, (GG) and round seed shape (WW) seeds are dominant traits, while green color or (gg) wrinkled shape (ww) seeds are recessive traits. You cross a pure breeding plant with yellow wrinkled seeds to a pure breeding plant with green round seeds to generate F1s. When you perform a reciprocal cross you get the same results. You take an F1 male and an F1 female to generate F2 offspring. You take an F2 male with rou and yellow seeds and mate them with an F2 female that has round green seeds. If these F2s produce 108 offspring, how many would be predicted to be green and wrinkled? a) 27 b) 3 c) 4 d) 7 e) 12

Tallness (T) in a certain plant is dominant to short (t), while red (R) flower color is dominant to yellow (r). The heterozygous condition results in orange (Rr) flower color. A short plant with red flowers, is crossed with a plant homozygous for tallness and yellow flowers. What would be the genotype and phenotype of the F1 individuals? ttRr—short and orange ttrr—short and yellow TtRr—tall and red Ttrr—tall and yellow TtRr—tall and orange
In tomatoes, red colour (R) is dominant over yellow colour (r) and tall plants (T) are dominant over short (t). Homozygous tall plants that produced red fruits were crossed with homozygous short plants that produced yellow fruit. What type of genotypes will be produced in F1 generation? O RETT, RRtt, ErTT O RRTT, rrtt O TtRr O RRtt and rrTT
In pea plants yellow seed color, (GG) and round seed shape (WW) seeds are dominant traits, while green color or (gg) wrinkled shape (ww) seeds are recessive traits. You cross a pure breeding plant with yellow wrinkled seeds to a pure breeding plant with green round seeds to generate F1s. When you perform a reciprocal cross you get the same results.

A. In corn, yellow kernels (Y) are dominant to white kernels (y). If you cross two plants with the Yy genotype, what percentage of the offspring will have yellow kernels? B.What percentage of the offspring will have the same genotype as the parent plants? C.Say you're also interested in corn plant height where tall plants (T) are dominant to short plants (t). You want to save some time and just cross your plants once. The P1 genotypes are YyTT and YYTt. Will you get any short plants with yellow kernels from this cross? Why or why not? D. If these traits, kernel color and height were linked, how would this affect your experimental outcomes? Would you expect the laws of Mendelian genetics to still apply? Why or why not ?
