A gardener grows two different colors of apples under exactly the same environmental conditions. Red apples have a heritability of 0.14 for the value of apple weight, and green apples have a heritability of 0.41 for the value of apple weight. The gardener plotted the number of apples present at each weight. Which graph would you hypothesize represents the red apples? Number of apples Weight GRAPH A Number of apples Weight GRAPH B O Graph A O Graph B There is not enough information to make a hypothesis.
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.
