The Scarborough shoal in the South China sea is home to the Peliotsky turtle. A recessive mutation "floppy" is known in the turtle which interferes with normal flipper growth and makes the turtle less mobile and unable to survive severe storms. In 2008 a sample survey of a large, freely interbreeding, population of turtles found 47 individuals with the mutant phenotype out of a population of 341 individuals. a) Calculate the frequencies of the recessive and dominant alleles in the turtle population.
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.
