Heredity
Why might a diploid organism produce haploid cells through the process of meiosis rather than simply undergoing mitosis?
Considering the varying crossover frequencies observed in different regions of a chromosome, which evolutionary advantage is most likely conferred by this non-random distribution of crossover events during meiosis?
If crossing over during prophase I occurs more frequently at telomeric regions than at centromeric regions, what could be inferred about the selection pressures acting on these chromosomal domains?
During which phase of meiosis are homologous chromosomes separated?
Why might crossing over process be particularly advantageous evolutionary speaking?
Given that some organisms exhibit polyploidy whereas others remain diploid or haploid throughout their life cycles, how does this genomic difference potentially affect speciation events?
Which observation from a genetic map most strongly supports the idea that two genes are closely linked on the same chromosome?

Which event during meiosis is essential for ensuring that each gamete receives only one set of chromosomes, thus maintaining species' chromosome number across generations?
During which phase of meiosis can crossing over, a process that increases genetic diversity within a species, most often occur?
If two parents are carriers for an autosomal recessive disorder, what is the probability that their third child will be affected if their first two children are unaffected?
