Chapter 14.1, Problem 2CC
WHAT IF? Ø List all gametes that could be made by a pea plant heterozygous for seed color, seed shape. and pod shape (YyRrli; see Table 14.1). How large a Punnett Square would you need to draw to predict the offspring of a self-pollination of this "trihybrid"?

A Heterozygous plant, GgHhliJjKk is allowed to self-fertilize. What is the probability that an offspring will be GgHHliJjKk?
DRAW IT Pea plants heterozygousfor flower position and stem length(AaTt) are allowed to self-pollinate,and 400 of the resulting seeds areplanted. Draw a Punnett square forthis cross. How many offspring wouldbe predicted to have terminal flowers and be dwarf? (See Table 14.1.)
Fruit weight is controlled by 4 gene pairs. The homozygous dominant weighs 200 g while the homozygous recessive weighs 80 g. Assume that the alleles have equal contribution and have cumulative effects. The F1 and F2 of the two parents below were studied.
Parent 1 - D1D1D2D2D3D3d4d4 x Parent 2 - d1d1d2d2d3d3D4D4
Compute for the contribution of the dominant allele.
Compute for the fruit weight of parental 1 and parental 2.

- What is the difference between self-pollination and cross-pollination? If pollen is transferred from the stamens of a flower to the stigma of the very same flower, is that cross-pollination or self-pollination? If it is transferredfrom the stamen of one flower to the stigma of another flower on the very same plant? If it is transferred from the stamen of one flower to the stigma of another flower on a different plant, but a plant that is a clone of the first one? Animals do not have pollen, of course, but why is it that most animals never have to worry about the equivalent problem of self-fertilization? Why cannot most animals fertilize themselves?arrow_forwardRound seed is dominant over wrinkled. Yellow cotyledon is dominant overgreen. Full pod is dominant over constricted.
