situation in which both alleles of a gene contribute to the phenotype of the organism
more than two possible alleles exist for that gene
traits controlled by interactions of several genes.
1. Each organism must inherit a single copy of every gene from its parents. 2. When an organism produces gametes, those two sets of genes must be separated from each other, so that each gamete contains just one set of genes.
Mendel's principles of genetics rely on two things...
a cell that contains both sets of homologous chromosomes
What is a diploid cell represented as?
a cell that contains a single set of chromosomes
process of reduction division in which the number of chromosomes is cut in half through the separation of homologous chromosomes in a diploid cell
Meiosis I and Meiosis II
What are the two main stages of Meiosis?
each chromosome duplicates
what happens prior to Meiosis I?
structure containing 4 chromatids that forms during meiosis
