Explain Each of the following to your neighbor

• Dominant Recessive• Incomplete Dominance• Co-Dominance• Multiple Alleles• Sex Linked• Dihybrid Cross

• In fruit shape is inherrited by Incomplete Dominance where oval shape results from an Long and Round allele. A plant producing some oval radishes is crossed with one producing only round radishes. Indicate the phenotypic ratio resulting in this cross

Tall, T, is dominant to short, t. Red flowers, R, are dominant to white flowers, r. A gardener crosses a

TtRr with a ttrr plant. What genotypes and phenotypes would

you expect to see in the F1 generation?

Color blindness is a sex linked recessive trait. A Hetrozygous normal woman whose mother was colorblind has a son. Nothing is known of the color-vision phenotype of the father. What is the chance that the son is colorblind?

In summer squashes, white fruit is due to a dominant allele (W), and colored fruit is due to its recessive allele (w). Disk -shaped fruit is due to a dominant allele (D), and sphere-shaped fruit is due to its recessive allele(d). In a cross between a squash plant with yellow fruit and heterozyous for disc shape and a Homozygous dominant white squah with a sphere shape, what phenotypes will appear in the first generation?

In humans, migraine (a type of headache) is due to a dominant factor (M). A normal-

• visioned woman who had never suffered from migraines takes her daughter to a doctor for

• an examination. In the course of the examination the doctor discovers that the girl is

• Colorblind (sex linked recessive) and suffers from migraines. What does the doctor automatically know about the

• father?

• In fruit flies, red eye, R is dominant to magenta-eye, r. Long wing, L, is dominant to miniature wing, l. Eye color and wing length are both sex linked. A red-eyed miniature winged male is bred to a magenta-eyed heterozygous long-winged female.
