Answer: Homologous chromosomes are pairs of chromosomes, one
from each parent, that are similar in shape, size, and genetic content.
◉ What is homozygous?
Answer: Homozygous refers to having two identical alleles for a
particular gene.
◉ What is heterozygous?
Answer: Heterozygous refers to having two different alleles for a
particular gene.
◉ What is a dominant allele?
