(3-LS3-1) Other characteristics result from individuals' interactions with the environment, which can range from diet to learning. That only happens at the start of meiosis I. Match the most related term with the description: Inability to achieve or maintain an erection. Based on the slide analysis, what would be the sex of the baby? Crossing over occurs only between nonsister chromatids within a homologous pair of chromosomes, not between the sister chromatids of a replicated chromosome. This produces a unique combination of genes in the resulting zygote. Clearly, the male and female flies were inheriting the trait in different patterns.
