In plants, you want to know whether two loci, P and Q, are linked and if so, what their map distance is. You do a testcross with a P/p●Q/q plant and observe the following progeny. Based on this information, what are the genotypes of the parents? Genotype Progeny P/p●Q/q 21 p/p●q/q 25 P/p●q/q 216 p/p●Q/q 238 a) The loci are linked and 4.0 m.u. apart b) the loci are linked and 18.4 m.u. apart c) the loci are linkd and...

In chickens, comb shape is determined by non-epistatic interactions between genes at two loci (R, r and P, p). A walnut comb is produced when at least one dominant gene R is present at one Single Rose locus and at least one dominant gene C P is present at a second locus (genotype R P ). A rose comb is produced when at least one dominant gene is present at the first locus and two recessive genes are present at...

Two plants in a cross were each heterozygous for two gene pairs (Ab/aB) whose loci are linked and 25 mu apart. Assuming that crossing over occurs during the formation of both male and female gametes and that the A and B alleles are dominant, determine the phenotypic ratio of their offspring. Please Explain your reasoning behind your answers and how you got to them. Thanks!

A pink-flowering plant is of genotype RW. If two such plants are crossed, we obtain a red plant (RR) with probability 0.15, a pink plant (RW or WR) with probability 0.68, and a white plant (WW) with probability 0.17, as shown in the table. What is the expected number of W genes present in a crossing of this type? The expected number of white genes (W) is (Type an integer or a decimal.)

15. You are studying com plants. You were able to determine that the gene for kernel color (C-colored and no color) and kernel waxiness (W = waxy and not waxy) are on the same chromosome and are 30 CM apart. You are ultimately interested in determining the potential phenotypic ratio if crossing over occurs. You start by crossing a male who is homozygous dominant for both genes with a female who is homozygous recessive for both genes. The F1 heterozygotes...
