Slide28 Opener 5/4-5/16A guinea pig breeder wants to know what fur offspring might have. They know that for color black fur is dominant over white fur and that long fur is dominant over Short fur. The male has short white hair and the female has long black fur. (Hint: first figure out what the male’s and female’s genes are)

1.Show the expected offspring of a F1 cross.
2.Carry out to the F2 generation a cross between a homozygous plain red bird and its homozygous checkered brown mate.
3.A plain brown female pigeon laid five eggs. The young turned out to be: 2 plain red, 2 checkered red, and 1 checkered brown. Describe the father pigeon. Give the genotypes of all birds in this cross. Could any other types of offspring have been produced by this pair?
Image A
• In pigeons the checkered pattern is caused by a dominant allele. •A plain (non-checkered) pattern is recessive. •Red color is also caused by a dominant allele and brown color by a recessive allele.

Autosomal —(Non-sex
cells)
Recessive
• If the disorder is dominant, one of the parents must have the disorder.• If the disorder is recessive, neither parent has to have the disorder because they can be heterozygous.
Autosomal
• If most of the males in the pedigree are affected the disorder is X-linked • If it is a 50:50 ratio between men and women the disorder is autosomal
Recessive —Parents
