The slipper orchid is a highly prized flower that undergoes self-fertilization. You own a slipper orchid that has the genotype Aabb. What will be the genotype of the plant’s offspring? a)All offspring will also be Aabb b)¼ AAbb, ½ Aabb, ¼ aabb c)½ Aa, ½ bb

CRCR (red flowers); CRCW (pink flowers); CWCW (white flowers); F (full leaves) > f (slender leaves); H (heat tolerant) > h (vulnerable to heat) G*G? (green leaves); GʻG? (green and yellow leaves); G?G² (yellow leaves) CRCR Ff Hh G1G1 x CRCW Ff hh GʻG? Box 1: Which trait displays incomplete dominance? Box 2: What is the PHENOTYPE of the second parent in the cross? Box 3: What is the probability of having an offspring which is completely HETEROZYGOUS? Show your work by listing the fractions and how you would determine the answer (add, subtract, divide, multiply, etc).

A purpled-flower plant (WW) is crossed with a white-flowered plant (ww). The F1 generation offspring are crossed with each other (selfing). Which of the following is the correct genotype of the F2 generation? A)WW, Ww, Ww, ww B)ww, ww, WW, WW C)Ww, Ww, Ww, Ww D)WW, WW, ww, Ww

Crossing-over   B.) Independent assortment   C.) Mutation

If you cross heterozygous spherical (S) yellow (Y) seeded plant with dented(s), green(y) the offsping and the ratio would be: A)F:SsYy, ssyy; ration 1:1B)F: SSYy, Ssyy, ssYy, ssyy; ration 1:1:1:1C)F: SSYy, Ssyy, ssYy,ssyy; ration 1:1:1:1D)F: SsYy, Ssyy, ssYy, ssyy ration 1:1:1:1

Consider a corn plant dihybrid for the traits of purple and smooth kernels. When allowed to self-fertilize, 489 offspring are produced. How many of these offspring are expected to exhibit the traits of yellow and smooth kernels?

In a particular plant, leaf color and leaf shape are controlled by two linked genes. Leaves of the wild-type plant are red. A recessive mutation in this gene causes white leaves. Wild-type leaves are pointed and a recessive mutation in this gene causes them to be smooth. The following cross was performed: Heterozygous red, pointed 43 white, smooth 42 red, pointed 8 white, pointed 7 red, smooth Homozygous white, smooth RESULTS: What is the recombination frequency between the gene for leaf color and the gene for leaf shape?
