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
Matching chromosomes from each parent are called homologous chromosomes. Diploid organisms have two copies of every gene. Matching genes from each parent occur at the same location on homologous chromosomes. A diploid organism can either have two copies of the same allele or one copy each of two different alleles. Individuals who have two copies of the same allele are said to be homozygous at that locus. Individuals who receive different alleles from each parent are said to be heterozygous at that locus. The alleles an individual has at a locus is called a genotype. The genotype of an organism is often expressed using letters. The visible expression of the genotype is called an organismâs phenotype.
