You have learned that purple flowers are dominant to white in Mendel’s peas. When walking the grounds of Mendel’s monastery, you come across a stray purple pea plant. You suspect that it is descended from Mendel’s experimental plants, but you have no idea of its exact heritage. Propose a way in which you could determine the plant’s genotype with respect to the flower color (Assume that you have any other pea plants that you might want to use in your analysis) A. which other plant(s) would you need in your experiments? (This means specific genotype or phenotype characteristics of them) (3.5 points) B. What do you expect to see? (expected results and interpretation) (3.5 points) C. Would this 100% let you determine the genotype of the purple plant? (3.5 points)

Late Paleozoic glacial deposits are NOT found in which of the following places?

Coat color in cats is determined by genes at several different loci. At one locus on the X chromosome, one allele (X+) codes for black fur; another allele (Xo) encodes orange fur. Females can be black (X+ X+) orange (XoXo)or a mixture of orange and black called tortoiseshell (X+ Xo). Males are black (X+Y) or orange (XoY). Patches is a female tortoiseshell cat that mated with a stray male. Patches later gave birth to the following kittens: one orange male, one black male, two tortoiseshell females, and one orange female. Which of the following represent the genotypes for Patches and the stray male?

In a dividing germ-line cell in a human male, when do the X and Y chromosomes segregate?
