Principles of Inheritance & Variation (Genetics)In a hypothetical plant assume that the color of the flower is under the control of a single gene Assume that the gene has two alleles the dominant allele R that corresponds to the color red and the recessive allele r that corresponds to the color yellow R Red r yellow Someone gifted you a plant with a red flower but you do not know for certain whether such plant is homozygous or heterozygous Rex Br CBS RE Br Br C RR x rr r 1 What type of cross should you perform to determine whether the plant is homozygous or heterozygous it is Heterozygous 2 You counted three offspring all with red flowers from the cross in question 1 You then concluded that your plant must be homozygous Two questions a Write a Punnett square that justifies such conclusion b What is the probability that your conclusion is WRONG i e your plant is instead heterozygous 3 Assume again that all offspring of the cross in question 1 are all red and that you conclude again that your plant must be homozygous How many offspring should you count to ensure that the probability of your conclusion being wrong is less than 0 001 i e you have less than 0 1 chance of being wrong
