Include in your discussion the factors that may contribute to the maintenance of genetic isolation. The arrows indicate reaction sites for two restriction enzymes enzyme X and enzyme Y. Describe how scientists use each of the following as evidence for evolution.

Include in your discussion a sample cross es sufficient to verify your proposed pattern. Describe a procedure by which this can be done.

Discuss how recombinant DNA techniques may be used to correct a point mutation. A portion of specific DNA molecule consists of the following sequence of nucleotide triplets. Calculate, showing all work, the frequencies of the alleles and the frequencies of the genotypes in a population ofrabbits, of which 25, are white and 75, are agouti.

A new population was created by crossing 51 pure breeding homozygous dominant individuals with 49 pure breeding homozygous individuals. In rabbits the white color is due to a recessive allele, w, and the agouti is due to a dominant all, W.
