Two different genes controlling pod morphology in peas are found on chromosome 5. The narrow pod trait is recessive to wide pods and yellow pods is recessive to green pods. A heterozygous plant is generated by mating a narrow green pod plant with a wide yellow pod plant. This plant was testcrossed and the following progeny were obtained. What is the linkage relationship between the two genes?

144 Narrow green pods , 150 wide yellow pods , 110 narrow yellow pods , 90 wide green pods

1. Genes A, B, and C are each located on a different chromosome type. Predict the phenotypic ratio in the progeny of the test cross: AaBbCc X aabbcc. Assume that capital letters represent dominant alleles and lower case letters represent recessive alleles. Use the symbols “A”, “B”, & “C” to represent the dominant phenotype specified by genes A, B, & C, and the symbol “a”, “b”, & “c” to represent the recessive phenotypes. 2. If genes A & B are...

We talked about the genes controlling our ability to digest lactose, the sugar found in milk. Collectively the enzymes produced by the set of genes involved are called lactase. "Lactose intolerance" describes the most common condition in human adults, which is an inability to digest lactose because lactase is not produced. These people could all produce lactase as infants, however, so they have the genes needed to produce functional enzymes. Somehow the regulation of expression of the genes changes as...

Suppose two genes determine shape and color of peas. Gene G codes for color and G is dominant. A pea that is GG or Gg is green, a pea that is gg is yellow. The gene R codes for shape. A pea that is RR or Rr is round, a pea that is rr is oval. If we cross two peas that are Gg and Rr we expect the following distribution of peas: (9/16) are green and round, (3/16) are...

There are two approaches to measuring non-controlling interests, each of which will lead to a different amount being attributed to reported goodwill. Will the choice of either method of accounting for non-controlling interests impact any goodwill impairment expenses that might subsequently be recognised?

Different genes will have different phylogenetic histories among two species. Explain this in terms of mutations and in terms of coalescence processes? Do different genes have different coalescence times? What is an adaptive radiation? Why is it significant that most adaptive radiation examples we use come from islands? -Why do we need different species concepts for fossils, for bacteria and other microbes, and for sexually mating organisms like most living plants and animals?
