In mammals, more than one chiasma per chromosome arm is an indication that crossing-over has occurred. Scientists compared the average number of chiasma among the species shown in the table. Based on the data, which of the following questions could be asked to determine how the genetic diversity of these mammals would be affected in future generations? A - Are baboons or dogs more genetically diverse? B - Are horses more genetically diverse than other mammals? C - Are baboons less genetically diverse than other mammals? D - Do horses and cats express a comparable amount of genetic variation?
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
