mendel used pea plants for his experiments because they had contrasting traits, they were easy to grow, and they produced large numbers of offspring in a short time. in addition, pea plants are pure - breeding plants. pure - breeding plants are plants that produce seeds that grow into offspring with the same characteristics as the parent plants, generation after generation. for example, pure - breeding tall plants always produce tall offspring and pure - breeding short plants always produce short plants. as a result of his experiments, mendel proposed that various characteristics of organisms are passed from one generation to the next by the transmission of pairs of factors, one factor from each parent. mendels factors are now called genes.

dominance. to find out how traits were passed from parents to offspring, mendel set up a series of experiments and carefully recorded his observations. in mendels first experiment, he took pollen from pure - breeding tall plants and transferred it to the pistil of pure - breeding short plants (cross - pollination). the purebred plants are called the parent (p) generation. the offspring of a cross between two parent (p) generation plants are called the first filial (f₁) generation. mendel observed that all the offspring in the f₁ generation were tall (figure 23 - 5). the trait for shortness did not appear.

Explanation:

Question 1

From the text, it says "Mendel used pea plants for his experiments...", so the organism used by Mendel in his heredity experiments is the pea plant.

In genetics, two different forms of the same trait (like tall and short for plant height) are known as alleles. This is a basic genetic concept related to Mendel's work on traits.

An intermediate form (where neither trait is completely dominant and the offspring shows a blend) is an incomplete dominance form. This is a genetic concept where the phenotype is intermediate between the two parental phenotypes.

Answer:

pea plant
