Genetic Drift Genetic drift‚ also known as allelic drift‚ is the change in the number of gene variants‚ alleles‚ in a population because of random sampling. The allele frequency in a population is the fraction of the copies of one gene that share a specific form. The alleles in the offspring are a sample of gene variants in its parents. Chance plays a part in whether one survives and carries its genes on‚ or does not. Genetic drift may cause gene variants to disappear completely resulting in reduced

body of research within health psychology has focused on not only the consequences of obesity but also understanding the causes of obesity‚ both genetic and environmental – this is what this essay will explore.... Genetics There have been several theories put forward by research to best explain the causes obesity and one major potential causes is genetics. Maffeis et al (1998) found that obesity in parents was the strongest predictor of childhood obesity‚ regardless of diet or level of activity

time per pair of homologous chromosomes -if recombination occurs‚ principle of independent assortment is not violated the distance between genes determines the frequency of crossing over‚ close together‚ cross over rare‚ far apart it is frequent Genetic Maps 20% of the offspring are recombinant‚ the two genes are 20 map units apart how many map units on chromosome ----- How often does this occur? If genes are more than 50 map units apart they will sort independently Cross
