Question 11 Which of the following examples is an example of epistasis epistatic effects O Individuals who have a heritable form of diabetes caused by a dominant allele vary significantly in their degree of sickness disease effects because those who eat much healthier and exercise regularly have better health and longer life than those who do not eat well or exercise regularly O Many long neck promoting and growth promoting alleles accumulate in a population of animals such as the ancestors of giraffes and over time the higher frequency of all these alles several genes results in a population of long necked individuals The recessive cystic fibrosis allele is removed from a population every time an individual which is homozygous for the disease allele does not reproduce In Himalayan Snow Leopards the production of Melanine is dictated by the expression of a single gene
