The alleles for type A blood and type B blood are said to be _______ over the allele for type O blood.

 If one parent is heterozygous for type A blood, and the other parent is heterozygous for type B blood, the probability of producing a child with type O blood is

When two or more genes are carried together during crossing over in meiosis, such that one phenotype is usually associated with another (e.g. eye color and wing length in fruit flies), those genes are said to be

Prokaryotes (bacteria and archaea) reproduce new cells by

Gregor Mendel examined seven characteristics of pea plants, including flower color. When he crossed pure-breeding purple flowers with pure-breeding white flowers, the first generation of offspring (F1)

Mendel proposed that each parent contributes one copy of a “factor” (gene).  Different copies, or alternate forms of the same gene (e.g. B, b) are called

When the phenotype of a heterozygote is an intermediate, or blend, between the phenotypes of pure-breeding parents (e.g. pink flowers from red and white parents), the two alleles/copies of a gene are said to be

The cell cycle is controlled by three checkpoints (G1, G2, and M).  These checkpoints depend on the action of

The primary function of mitosis is to

If an mRNA codon reads UAC, its complementary anticodon on a tRNA will be
