Concept explainers

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 fac…

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 clas…

Textbook Question

Chapter 23.3, Problem 3CC

WH AT IF? → Suppose two plant populations exchange pollen and seeds. In one population, individuals of geno-type AA are most common (9.000 AA. 900 Aa. 100 aa), while the opposite is true in the other population (100 AA, 900 Aa, 9.000 aa). If neither allele has a selective advantage, what will happen over time to the allele and genotype frequencies of these populations?
