One gene pair is involved. What type of inheritance is shown in the pedigree above? Choose all that apply.

A testcross can be done to determine the genotype of an individual expressing dominant traits or to determine the relative distance between two or more linked genes.

With incomplete dominance, a likely ratio resulting from a monohybrid cross would be:

Two linked genes (A) and (B) are separated by 18 mu. A man with genotype AaBb marries a woman who is aabb. The man’s father was AABB. What is the probability that their first child will be Aabb?

Maternal effect molecules are products of the mom’s genotype that are placed in an egg.

1) In sex-limited inheritance, only one sex shows the trait.  2) In sex-influenced inheritance, the heterozygotes show different phenotypes depending on sex.

The discipline within evolutionary biology that studies changes in allele frequencies is known as ________.

For a sex-linked trait with two alleles, dominant X+ and recessive Xa, one can determine q by knowing the percent of males that exhibit the recessive trait within a population. 

Crossing over occurs specifically during:_________________________________. 

Many species have two representatives of each chromosome. In such species, the characteristic number of chromosomes is called the ________ number. It is usually symbolized as ____.
