Recessive epistasis: In a cross between fruit flies that are both double heterozygous for modifier gene and coat color, in the total offspring of 192, how many fruit flies have gray- coat, white coat, and black coat? A recessive allele blocks the expression of the coat color of fruit flies. Make a null hypothesis, compute for chi-square and determine if the null hypothesis is accepted or rejected.Show your answer, table, punnet square, and solution.
