Question

Based on the model, what claim was the student most likely making?

The variation in pelvic spines resulted from errors during protein synthesis.
The variation in pelvic spines resulted from errors occurring during replication.
The variation in pelvic spines resulted from changes to the chromosomes that occur during mitosis.
D The variation in pelvic spines resulted from sections of chromosomes exchanging places during meiosis.

Answer 1

It is not specified in the question what the student is referring to when they mention "variation in pelvic spines" and it's also not specified if the student is talking about human or animal, so it's impossible to give a correct option. However, option D) "The variation in pelvic spines resulted from sections of chromosomes exchanging places during meiosis" is a possible explanation for the variation in pelvic spines. During meiosis, the process of cell division that creates sperm and egg cells, chromosomes can exchange pieces of DNA through a process called crossing over. This can lead to variations in the genetic makeup of the cells produced, which could potentially result in variations in physical characteristics such as pelvic spines.
