Assignment:

A) Compare the meanings of the following word pairs:

Dominant versus recessive alleles
Genotype versus phenotype
Homozygous versus heterozygous

B) Why is it that the dominant phenotype of some characteristics is quite rare in a population and the recessive phenotype is much more common?

C) Define what is meant by Mendel's Second Law, the Law of Independent Assortment. How does a knowledge of this law help us to predict the frequencies of each gamete type produced by an individual of genotype AaBb if we know that gene A is located on a different chromosome type than gene B?

D) Draw a Punnett square for the cross Aa x aa. Be sure to indicate the different gamete types each parent can produce (in their proper place on the square) as well as the genotypes of all possible offspring. You may have to use the "Table" tool above to make your Punnett square.

E) What is different between autosomal and sex-linked inheritance? How might one be able to determine that a particular trait is autosomal or sex-linked?
