If two genes (A & B) are 26 centiMorgan (cM) apart on the same chromosome, what are the probability for the offspring to display a recombinant phenotype following the cross of a heterozygous parent (AaBb) with a homozygous recessive parent (aabb)?

Below is a pedigree tracking a genetic disorder in a family. Squares represent males, circles are females. Affected individuals are shaded in black, whereas healthy individuals are in white. Based on the chart below, how is this disorder most likely to be passed from parents to offspring?

Down’s Syndrome is an example of ____.

When homologous chromosomes of sister chromatids fail to separate properly during meiosis, we call it ____.

Continuing from the question above, why do all the male kittens from this cross have orange fur?

If the allele controlling a dwarfism disorder is dominant, why do most people in the world have normal heights?

The fur color of cats is determined by a gene located on the X chromosome, With the XR allele codes for orange fur, and the XB allele codes for black fur. When a black male cat and an orange female cat mate, they give birth to only orange males and tortoiseshell (a mixture of both black and orange fur) female kittens. Based on the above information, What are the genotypes of the parent (P) generation male and female cats in this cross? Note: Do not consider sample size, just the fact that all male offspring are orange and all female offspring are tortoiseshell.

The location of a gene on the chromosome is called its _____.

What are enhancers, regulatory elements, promoters, and operators?

Antigenic variation is effective against ____.
