Concept explainers

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.

Question

Which of the following scenarios were most likely lead to a change in DNA that would increase genetic variation in the individuals offspring

UV radiation mutates the skin cells of a pregnant mother, changing two G bases to T
bases.
An A - T base pair changes to a C - G base pair during mitosis in a liver cell of a young
man
AG-C base pair changes to an A - T base pair randomly during meiosis in a young
woman.
A virus inserts nine base pairs into a lung cell of an elderly man.

Which of the following scenarios would most likely lead to a change in
DNA that would increase genetic variation in the individual's offspring?

Definition Definition Genetic variation refers to the differences in DNA sequence among individuals of the same species. These variations can occur due to mutations, genetic recombination, and natural selection. Genetic variation plays an important role in evolution, as it allows for the selection of traits that enhance the survival and reproduction of organisms in changing environments.

Malaria, one of the most pervasive and destructive of all infectious diseases, is caused by protozoan parasites of the genus Plasmodium, which are transmitted from person to person by mosquitoes. Plasmodium parasites are able to evade the host immune system by constantly altering the expression of their var genes, which encode Plasmodium surface antigens (L. H. Freitas-Junior et al. 2005. Cell 121:25–36). Individual var genes are expressed when chromatin structure is disrupted by chemical changes in histone proteins. What type of chemical changes in the histone proteins might be responsible for these changes in gene expression?
