mating of two organisms that differ intwo characteristics
descriptive pf an allele in a heterozygour individual that appears to be the only one affecting a trait
egg or sperm sex cell that contains a single set of chromosomes, one from each homologous pair
specific location of a gene on a chromosome

study of heredity
genetic makeup of an organism; an organism's combination of alleles

inheritance in which heterozygotes have a phenotype intermediate between the phnotypes of the two homozygotes
process by which the nucleus and duplicated chromosomes of a cell divide and are evenly distributed, forming two daughter nuclei
