In cattle, the gene for straight hair (H) is dominant to the allele for curly hair (h). The genes for red (RR)
or white hair (R'R') coat colors show codominance. Heterozygous for color show a roan coat (RR') with
both red and white intermixed hair.
1. A curly red cow is mated to a homozygous straight haired white bull.
x Cow =
a. What is the genotypes for the parents: Bull =
The egg cell?
b. What letters will you use for the sperm cell?
d. Show the Punnett Square here:

You can tell from this karyotype that the individual is female because the karyotype has two chromosomes labeled

The blue particles in this image are able to cross the cell membrane through simple diffusion. how will they be transported? outside the cell inside the cell o a. the substances will move directly across the membrane from outside the cell to inside the cell. b. the substances will move through channels in the membrane proteins from outside the cell to inside the cell. o c. the substances will move through channels in the membrane proteins from inside the cell to outside the cell. o d. the substances will move directly across the membrane from inside the cell to outside the cell.

The frequency of alleles in a population that is in hardy weinberg equilibrium? a . changes in each successive generation b. is less important than the frequency genotypes c. shows evidence of the process of natural selection d. remains the same over several generations
