When Mendel examined the inheritance of pod colour, he crossed true- breeding green and true-breeding yellow plants. All of the plants produced were yellow. He then crossed the yellow plants and found that some of the offspring were green and some were yellow. What did he conclude from this? * O a) yellow is dominant to green O b) the F1 generation was heterozygous c) each trait has two factors O all of a, b, and c both a and c
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.
