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

How do most autosomal recessive
alleles, that lead to lethal diseases,
persist in human populations?
The disease-causing allele can
"hide" in the heterozygous
condition.
These diseases only affect
individuals who are XY.
These diseases usually take effect
later in life after people have had
children.
The environment plays a large role
in determining whether the gene is
expressed.
