Pairs of chromosomes that are not identical but have genes for the same trait arranged in the same order Homologous Chromosomes Each pair of cells has one chromosome from the mother and one chromosome from the father
gene Units of information about specific traits, passed from parents to offspring. Each gene has a specific location (locus) on a chromosome and may come in several forms (alleles). genotype The actual genes for a trait present in an individual.genotypic ratio The expected numbers of different genotypes produced by a particular cross. single (before replication) or double (after replication) strand of DNA with only a single centromere. Chromosomes contain the loci for alleles of different genes. The illustration below shows a chromosome with the parts labeled before (on the left) and after (on the right) replication.
