Difference between homologous and homozygous??

Dear student, In genetics, two chromosomes located on the same position on a karyotype are said to be homologous chromosomes. For example, the two chromosomes located at pair number one in a human karyotype are homologous chromosomes. The term homozygous in genetics refers to the situation where two genes or alleles for a particular trait are the same on a pair of homologous chromosomes. For example, in pea plants, if both height genes for the trait of height in a particular plant are tall, then that plant is said to be homozygous tall. Regards
