Mendel selected pea plants for his experiment because of the following reasons . Gregor Mendel decided to study heredity because he was working in the garden and saw different traits about plants and got curious. DNA can be directly or indirectly damaged by any ionizing radiation such an x-ray; the radiation may kill the cells or cause genetic injury, which may affect the cell’s ability to reproduce itself correctly and cause mutation. What is the probability that the offspring will have wrinkled seeds? This indicates how strong in your memory this concept is. That is, plants with purple flowers always produced seeds that generated purple flowers. Mendel selected garden pea for his experiment because of the following reasons:(i) Garden pea have a sort lifecycle and thus can produce more number of offsprings in a short duration. If a child has freckles, at least one parent has freckles. Gregor Mendel chose pea plants for his experiments because they are easy to raise, have many offspring per mating, can fertilize themselves and have varieties in genotype and phenotype that are easily observable.

Mendel worked on pea plants because they had a variety of desirable traits. Though farmers had known for millennia that crossbreeding of animals and plants could favor certain desirable traits, Mendel's pea plant experiments conducted between Why? Furthermore, pea plants grow quickly, so he could complete many experiments in … Why are nonrenewable energy sources important to humans? Mendel chose garden pea (Pisum sativum) as plant material for his experiments, since it had following advantages: 1. Pure breeds were important in his experiment so he could record accurate results. Transposons are DNA sequences that move from one place to another on the genome. Answer: They reproduce sexually. gen73 Gregor Mendel conducted hybridization experiments on around 29,000 pea plants. Introduces Gregor Mendel and illustrates the experiments he used to identify dominant and recessive traits.. % Progress . he specifically studied pea plants because they are self pollinating, they grow fast, and they have many different traits. Although the pea plants seem to have worked perfectly, I would have picked orchids. i believe it would cause an increase of percipitation, though i could be wrong. There were three main steps for Mendel's experiments: 1-By self-fertilization produced a generation of pure plants (homozygotes). He used garden peas for his experiments. Mendelian inheritance is a term arising from the singular work of the 19th-century scientist and Austrian monk Gregor Mendel.
