5 True/False Questions
gene: → To fertilize eggs with sperms from the same individual.
recombinant → (1) In general, any process in a diploid or partly diploid cell that generates new gene or chromosomal combinations not previously found in that cell or in its progenitors. (2) At meiosis, the process that generates a haploid product of meiosis whose genotype is different from either of the two haploid genotypes that constituted the meiotic diploid.
homozygous dominant → The phenotype shown by a heterozygote.
homozygous recessive → Refers to a genotype such as a/a.
independent assortment → The basic unit of eukaryotic chromosome structure; a ball of eight histone molecules that is wrapped by two coils of DNA.
