1 Q1. How does meiosis produce new genetic combinations? A. Random assortment of sister chromatids B. Random assortment of homologous chromosomes C. Crossing over during prophase II D. Fusion of gametes from two different individuals Q2. Is self-fertilization the same as asexual reproduction? A. Yes, because self-fertilization involves mitosis, not meiosis B. No, because self-fertilization involves meiosis C. Yes, because the offspring are identical to the parent in both cases D. No, because mutation rate is increased in self-fertilization Q3.Which gametes could this individual produce? A.

It is possible to predict the actual genotype of a single offspring if the parents’ genotypes are known. Q5. What makes an allele dominant ? A. It is expressed in both homozygotes and heterozygotes carrying the allele. B. It is the most common allele for that gene in the population. C.
