●● What is a diploid cell?
Answer: A diploid cell is a cell that has 46 chromosomes and two sets of
23 chromosomes; it is a somatic cell.
●● What are homologous chromosomes?
Answer: Homologous chromosomes are pairs of chromosomes that have
the same genes, one from each parent.
●● What are non-homologous chromosomes?
Answer: Non-homologous chromosomes are chromosomes that encode
for different genes.
●● What is the chromosome composition of human cells?
Answer: In a human cell, there are 22 autosomal chromosomes and 1 sex
chromosome, totaling 46 chromosomes.
●● What is a diplontic lifecycle?
, Answer: In a diplontic lifecycle, the adult is a diploid, starting from a
diploid zygote that undergoes mitosis.
●● What is a haplontic lifecycle?
Answer: In a haplontic lifecycle, the only haploid cells are the gametes
(sperm or egg).
●● How does sexual reproduction create genetic variation?
Answer: Sexual reproduction produces genetic variation through
crossing over during meiosis.
●● How does asexual reproduction differ in genetic variation?
Answer: Asexual reproduction usually results in less genetic variation,
as the new cells are exact copies of the parent cell.
●● What is a zygote?
Answer: A zygote is formed when an egg is fertilized by sperm.
●● What are alleles?
Answer: Alleles are different versions of a gene that encode for the same
trait, such as eye color.
●● What is the role of mitosis?
