In crook-necked squash, neck length is controlled by one gene where long neck is dominant over short neck. However, an intermediate phenotype, thick neck is a result of the heterozygous genotype. A. A long-necked and a short-necked plant are mated with each other. What is the resulting phenotype in the offspring?
B. If the offspring are mated with each other, what phenotypes (and in what ratios) will result?
