An example of a two allele determination of linkage.

A female animal with genotype A/a B/b is crossed with a double recessive male (a/a b/b). Their progeny include 442 A/a B/b, 458 a/a b/b, 46 A/a b/b and 54 a/a B/b. Explain.

A brief description of mutant phenotype classes: null, hypomorph, hypermorph, neomorph, and anitmorph.

What are the classes of mutant phenotypes and their definitions?

DNA transcription and translation.

The following DNA sequence is on the template strand of a DNA molecule being transcribed: T A C C G A T G A C C G A T T A.What is the complementary RNA strand that is formed? B.Assuming this sequence is within an exon and in-frame, what would be the polypeptide formed from it?

Determining why there is no phenotype change after a genetic mutation.

A single base-pair mutation in the gene of a model organism has been found. However, an individual homozygous for this mutation shows no phenotype. How is this possible?

Determining the genotypes and phenotypes in X-linked traits.

Follow an X-linked recessive mutation from a cross between a heterozygous female and a wild-type male. What would the genotypes and phenotypes of the F1 offspring be? F2?
