A professor is a member of a professional organization and is mostly interested in the newsletters sent and in participating in conferences. Which benefit is the professor primarily seeking?

Which letters does fertilization occur? 

Suppose the aa genotype  results in deafness.  If two heterozygous parents had four children, then 

The nurse cares for a client diagnosed with liver failure who reports bloating and tighness in their legs. The nurse notes generalized edema and ascites.  Which is most likely the cause?

A geneticist is mapping the chromosomes of the newly captured gremlin. Stripe is heterozygous for three linked genes with alleles Bb, Ee, and Hh that determine if gremlins have biting teeth (B), are evil (E), and have hair (H). In order to determine if the three genes are linked, a standard testcross was done, and the 1000 offspring had the following genotypes:   48        bb ee Hh 36        Bb ee hh 400      Bb ee Hh 4          Bb Ee Hh 426      bb Ee hh 46        Bb Ee hh 38        bb Ee Hh 2          bb ee hh (1) What is the recombination frequency between genes E – B? (2) What is the recombination frequency between genes E – H? (3) What is the recombination frequency between B – H?

Assuming three genes are incompletely linked, how many recombinant genotypes would you expect and at what frequency relative to independent assortment?

In certain goat breeds, appearance of a chin beard is a sex-influenced trait. Recall that bearding is inherited as an autosomal trait determined by two alleles, B1and B2, and females must be homozygous for the bearded allele, B2, to have a beard. What genotypes must a bearded billy goat (male) and a beardless female goat have if they have a bearded female offspring?

Choose the diagram illustrating the alleles on homologous chromosomes for the genotype DFg/DFG, assuming that the genes reside on the same chromosome in the order written.

The hairless allele (HL) in Mexican hairless dogs is dominant. A cross between two Mexican hairless dogs yields offspring which are 1/3 hairy and 2/3 hairless. What do these F1 ratios suggest about the hairless allele HL?
