Suppose you perform a monohybrid cross of two pea plants. the plants are heterozygous at the locus for stem height. t is dominant to t. t confers tall plant height. when you count the progeny, you find that there are 188 tall plants and 62 short plants. does this approximate the 3: 1 phenotypic ratio caused by mendelian inheritance? a.no, you would expect there to be more short plants. b.yes, there are approximately 3 short plants for every tall plant. c.no, the number of each phenotype is not in the exact ratio of 3: 1. d.yes, there are approximately 3 tall plants for every short plant. submit for grading save and finish later

Tall pea plants are dominant over short pea plants. can a short pea plant ever be produced from crossing two tall pea plants? a. no, only short pea plants can produce short pea plants because it is a recessive trait b. no, short pea plants are a different type of pea plant and could never be the offspring of tall pea plants. c. yes, two heterozygous tall plants could produce short pea plants. d. yes, two homozygous tall pea plants could produce short pea plants.

During his first set of experiments, mendel crossed true-breeding plants that expressed different versions of a studied trait. for example, he crossed tall plants with short plants. based on his results, he said the tall plants exhibited the dominant form of the trait, plant height. which of the following best describes the f, offspring of this cross? o a. about 25% were tall. o b. about 25% were short. o c. all were tall. o d. all were short
