A recessive allele is one:

Matt is normally pigmented but has an albino son.  Matt is ____________ for this trait.

After mitotic cell division, if a parent cell has 8 chromosomes, each daughter cell will have ______chromosomes.

This autosomal recessive condition is caused by a defective enzyme that produces the pigment melanin.

In snakes, the albino condition is recessive to normal pigmentation.  An albino female snake mates with a normally pigmented male snake. Their offspring are: 3  normally pigmented: 1 albino   What is the genotype of the male parent snake?

In pea plants, inflated pod is dominant to wrinkled pod.  A homozygous inflated pea plant is crossed with a wrinkled pea seed plant. What would be the expected phenotypic ratio of the F2 generation?

A pure-breeding red flower plant is crossed with a pure-breeding white flower plant. All of the offspring have pink flowers. If two pink flowered plants are crossed with one another, what results would appear?

Pluripotent stem cells change their gene expression pattern become other  more specialized cells.  These new cells have become:

The offspring of a true breeding long (L) eared dog crossed with a true breeding short (S) eared dog are all medium eared. This is a case of incomplete dominance. What is the genotype of the medium eared offspring?

Eukaryotic chromosomes are often represented in the shape of an ‘X.’ The two halves of a eukaryotic chromosome are joined together at a region known as the centromere. Each half of a eukaryotic chromosome is referred to as a:
