The results of a study of a population is presented in the following table
The "-" indicates that the other allele is unknown Parent1 phenotype Parent 2 phenotype Ratio and phenotype of offspring S - S - 989 S - 53 ss ss S - 560 S- 200 ss ss ss 700 ss Which of the conclusions listed below is correct? A. All of the S - offspring from the S - X S - matings are homozygotic B. If the S- offspring of the S - X S - matings were mated to the S - offspring from the S - X ss matings there would be no ss offspring all would be S - C. The ratios of the offspring in the S- X S - matings conform to the expected ratio for a monhybrid cross D. The ratios of the offspring in the S - X S - matings are due to some S - parents being homozygotic and some being heterozygotic Blooms Level:
