In the Eruopean Land snail, multipe alleles at a single locus determine shell color. The allele for brown (SB) is dominant to the allele for pink (SP) and to the allele for yellow (SY). PInk is recessive to brown, but dominant to yellow. a. In a population of 1000 snails, 160 are yellow. Assuming the populations is Hardy-Weinberg Equilibrium, calculate th frequency of the yellow allele, r = f(SY) = ? b. Given that p = f(SB) = 1. Calculate...

In the snail Cepaea nemoralis, an autosomal allele causing a banded shell (B ) is recessive to the allele for unbanded shell (O ). Genes at a different locus determine the background color of the shell; here, yellow (Y ) is recessive to brown (Bw ). A banded, yellow snail is crossed with a homozygous brown, unbanded snail. The F1 are then crossed with banded, yellow snails (a testcross). What will be the phenotypic classes resulting from a testcross if...

A population of flour beetles has 1000 individuals. Normally the beetles are red in color; however, this population has a utation in the gene for body color that results in black beetles that are designated by the rr genotype. Red body color is dominant to black so the genotypes RR and Rr result in red beetles. Assume the population is in Hardy-Weinberg equilibrium, with a 50% frequency of each allele for body color. A) --- what is the frequency of...

Two independently assorting genes help determine fruit color in squash. At the first locus, the W allele codes for a dominant white phenotype, whereas the w allele allows colored squash. At the second locus, the allele Y codes for a dominant yellow phenotype, and the allele y codes for a recessive green phenotype. The interaction between these two genes is an example of dominant epistasis, with the W locus acting as the epistatic locus and the Y locus acting as...

In sweet peas, two genes (genes A and B) control flower color. The dominant alleles of both genes produce enzymes that function in the biochemical pathway shown to convert colorless precursors to a purple pigment. The recessive alleles do not produce enzyme. Therefore, at least one dominant allele of both gene A and gene B are required for purple flowers. Answer the questions about this biochemical pathway.
