Which of the following can occur because of the exchange of homologous
parts during the process of meiosis?
Random mutations
Decreased gamete number
Offspring with unique combinations of traits
Decreased number of alleles on each chromosome

During meiosis, homologous chromosomes line up and exchange genetic material in a process known as crossing over. This genetic shuffling is what leads to offspring with unique combinations of traits, giving rise to diversity within a species—an essential component of evolution!

It’s important to note that this exchange of genetic material does not actually decrease the number of alleles on each chromosome; instead, it can increase the variability of alleles within a population. Such diversity is crucial for adapting to changing environments and overcoming challenges in survival.
