You cross two pea plants both from pure breeding lines.  One has hairy leaves and the other has smooth leaves.  All the offspring have hairy leaves.  If you take one of the offspring (F1) and cross it back to smooth-leaved plant what phenotypic ratio do you expect in the next generation? Group of answer choices A. half smooth and half hairy B. all smooth C. all hairy D. 3/4 hairy and 1/4 smooth

In four-o'clocks, the allele for red flowers is incompletely dominant over the allele for white flowers, so all heterozygotes have pink flowers. If you cross a white flower with a pink flower, what is the phenotypic ratio of the F1 generation (i.e., the offspring that are produced)?   a. 1 red: 2 pink: 1 white   b. 0 red: 2 pink: 2 white   c. 1 red: 0 pink: 3 white   d. 1 red: 1 pink: 2 white   e. 0 red: 4 pink: 0 white

Two genes control fruit color in tomatos. Plants of genotype AABB were mated to plants of genotype aabb. The F, were intermated to produce an F2 generation that consisted of 109 orange, 455 red and 36 yellow fruited plants. Which type of epistasis appears to be operating here? Select one: a. Duplicate Genes with Cumulative Effect O b. Single Recessive Epistasis Dominant/Recessive Interaction O C. O d. Single Dominant Epistasis O e. Duplicate Dominant Epistasis O f. Duplicate Recessive Epistasis

The term cross refers to an experiment in whicha. the gametes come from different individuals.b. the gametes come from a single flower of the sameindividual.c. the gametes come from different flowers of the sameindividual.d. both a and c are true

T = Tall t = short pollen from a tall pea plant T T eggs from a tall pea plant T TT TT t Tt Tt In the square shown, which of the following is true about the offspring resulting from the cross? Multiple Choice a. Half are expected to be short. b. All are expected to be tall. c. All are expected to be short. d. All are expected to be of medium height.

A plant that is homozygous for the recessive yellow pod color is crossed with a plant that is heterozygous. Which phenotype will appear MOST in the offspring?   A. There will only be plants with green pods.   B. There will be more plants with green pods.   C. There will be more plants with yellow pods.   D. Plants with yellow and green pods will appear in equal numbers.

whats the answer for #2 and is #1 correct?

You cross a pea plant with the genotype AaBbCcDd to one with the genotype AabbCcdd. What is the chance that the offspring is  aabbccDd? a. 1/128 b. 1/256 c. 1/64 d. 1/4

You have a pure breeding line of tall corn and a purebreeding line of short corn.  When you cross them what do you expect the phenotype of the F1 to be? Group of answer choices A. impossible to tell with the information given B. all medium height C. 3/4 tall and 1/4 short D. all short E. all tall

If you crossed an F1 plant with a plant that was homozygous recessive for both genes (yyrr),how would the phenotypic ratio of the offspring compare with the 9:3:3:1 ratio seen here?
