During mendel's first set of experiments, he allowed true-breeding tall plants
to cross with true-breeding short plants. what happened when he allowed the
f, offspring from this first set of experiments to self-pollinate?

Explanation:

What Mendel wanted to happen was to obtain middle-sized plants. What actually happened was that Mendel got tall plants. Due to this result, Mendel called Reccesive to the genes thatdetermined the short offspring, and Dominant to the genes that determined the tall offspring.

i think the answer would d

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
