How does this large sample size make his results more reliable? O A. He was not sure which of the plants were female and which were male. B. Most of the plants were unable to reproduce, so he needed many of them. C. He used more plants so the experiment wouldn't take as long. D. It made his actual results approach the results predicted by probability. SUBMIT E PREVIOUSClassical Mendelian Genetics, Incomplete Dominance, Codominance, and Multiple Alleles 1.

The crosses are lled ssed differently in homozy- heterozygous individuals. This produces a con- dition called incomplete dominance. In such cases, both worked out in the same manner as indicated previously, but heterozygous offspring exhibit a phenotype interme- diate between that of the homozygous individuals. Some examples follow. Activity 2 Working Out Crosses Involving Incomplete Dominance 1. The inheritance of flower color in snapdragons illustrates the principle of incomplete dominance. The geno-type RR is expressed as a red flower, Rr yields pink flowers, and rr produces white flowers. Work out the following crosses to determine the expected phenotypes and both genotypic and phenotypic percentages. % of each phenotype: 2.
