To determine:

Expected weights in the F₁ progeny if genotype AABB is crossed with aabb.

Introduction:

In the given scenario, it is supposed that plant weight is determined by a pair of alleles at each of two independently assorting loci (A and a, B and b) that are additive in their effects. The alleles represented by uppercase letters contribute 4 grams to plant weight, while the alleles represented by lowercase letters contribute 1 gram to plant weight.

(a)

Expert Solution

Explanation of Solution

The cross between AABB and aabb is as follows:

Parents ♂ ♀ AABB × aabb ↓ ↓ Gamates AB ab ↘ ↙ ↓ F1 generation AaBb

F₁ (filial 1) generation is AaBb. Its weight can be determined as weight contributed by A + weight contributed by a + weight contributed by B + weight contributed by b (4 + 1 + 4 + 1). So, the plant weight in F₁ generation would be 10 grams.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
