During his study of the rare Idlewild Lady Slipper (a wild orchid), Dr. Jorge Whiteback discovered several variants of the typical “wild-type” phenotype. He found two varieties of lady slippers at different elevations: a lady slipper variety found in the valley with red flowers and a lady slipper found at higher elevations with white flowers. When Dr. Whiteback did controlled crosses between lady slippers with red flowers and lady slippers with white flowers, all the offspring of this cross had pink flowers. After allowing pink flowering lady slippers to self-fertilize, the next generation of plants had 112 red flowering plants, 218 pink flowering plants, and 108 white flowering plants. part a)What mode of inheritance would best explain the results of Dr. Whiteback’s crosses? part b)How many genes and how many different alleles of these gene(s) are determining flower color according to your mode of inheritance? c) Define alleles using the appropriate notation for your answer in (a) and use that notation predict the results of a cross between pink flowering lady slippers and white flowering lady slippers. Predict the genotype(s) and phenotypes(s) of the offspring of this cross and the proportions of each. Show all work and clearly label all answers. ?
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.
