In mice, a white coat (W) is dominant over a brown coat (w). If a heterozygous mouse is mated with a brown mouse, what is the liklihood of them having a brown baby mouse?

One of the genes for colour vision in humans is "sex linked". Which chromosome carried the copy of this gene?

Colour blindness in humans is recessive and sex-linked. A colour blind male has children with a woman with normal vision. If they have a male with colourblindness, what is the genotype of the mother?

The gametes of a plant of genotype FfHh should have the genotypes:

Crossing over is an event that occurs at the end of:

The point where chromosomes cross over is called the:

In horses, a gene for coat colour has two alleles: red (R) and brown (r). When a purebred red cow is mated with a pure bred brown bull, all their calves have coat colours made up of a mixture of individual red hairs and brown hairs - known as Roan. This is an example of:

During which phase of Mitosis do sister chromatids separate?

During which phase of Mitosis do chromosomes line up at the equator of the cell?

At the end of Meiosis I, the daughter cells created are:

Oogenesis results in the production of:

Spermatogenesis results in the production of:

In squash, white fruit (W) is dominant over yellow (w) and disk-shaped fruit (D) is dominant over sphere-shaped (d).. If a squash plant true-breeding for white, disk-shaped fruit is crossed with a plant true-breeding for yellow, sphere-shaped fruit, what will the phenotypic ratios be for the offspring:

In squash, white fruit (W) is dominant over yellow (w) and disk-shaped fruit (D) is dominant over sphere-shaped (d). If a plant true-breeding for white, disk-shaped fruit is crossed with true-breeding for yellow, sphere-shaped fruit, what will chance be of getting a yellow sphere-shaped fruit in the F2 generation?

In rabbits, grey hair is dominant to white hair. Also in rabbits, black eyes are dominant to red eyes. What is the phenotype of a rabbit with the genotype Ggbb?

A male rabbit (BBee) is crossed with a female rabbit with the genotype (bbEe). What is the chance of having Black-Haired & Floppy-Eared bunnies?

Meiosis is a process that occurs in the:

There are no carriers for Huntington’s Disease- you either have it or you don’t. Is Huntington’s disease caused by a dominant or recessive trait?
