On the ribosome, there are three active sites. Which site allows an empty tRNA to leave?

The allele E allows for a another gene, a pigment gene, to make Black coat color in dogs (B for black or b for chocolate).  if the dog is ee, then the other B/b gene is shut off completely and the dog is yellow.  The E/e allele would be what type of inheritance pattern?

In flies, white eyes are sex-linked and reccessive to red eyes. If a heterozygousred-eyed female bred with a white eyed male, what ratio of the male offspring would be white eyed.

If R is red flowers and W is no pigment or white flowers and an RW is a pink flower, this would be an example of what type of inheritance?

Occasionally during meiosis, homologues fail to seperate causing the gametes to have an extra chromosome like as seen in children with Down syndrome.  The failure to seperate is called what?

of the 23 pairs of chromosomes that humans have, 1 pair are the X and Y chromosomes and are called what?

A dihybrid cross like PpTt x PpTt results in what phenotypic ratios?

Let P = puple flowers, p is white. T is a tall plant and t is short. What are the possible gamets for a plant that is heterozygous for both traits?

The amino acids are brought in and matched to the codons on the mRNA by what molecule?

The law of _ states that two alleles for a gene will seperate in the formation of a gamete.
