Consider a cross of beetles with exoskeleton alleles b and b and leg size alleles n and n. the maleparent is heterozygous in both traits. the female parent is homozygous recessive in both traits. a.write the four letter genotype for each parent. b.use the punnet square below to find the possible allele combinations for an offspring. possible allele combinations from the malebnbnbnbnpossible allelecombinationsfrom the .what is the probability that the offspring will have a genotype of bbnn? 4/16d. show how statistics could be used to calculate the probability you found in part c withoutusing a punnett square.
