The APsolute Recap: Biology Edition - Chromosomal Inheritance
Sexual reproduction increases genetic diversity in Episode 37. Chromosomes are tightly coiled DNA (1:00) and organized in homologous pairs (1:45). The three primary sources of variation within the population are chromosome segregation, independent assortment, and random fertilization (2:15). Do you remember Mendel’s laws? Some chromosomal errors cause genetic disorders (3:20). We can use pedigrees to find patterns in genetic traits (4:20).
The Question of the Day asks (5:42) “During what phase of meiosis does crossing over occur? ”
