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

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.
