Form of ripe seed -Smooth or Wrinkled (trait r chr 7) 2. True-breeding pea plants were important because Mendel didn't want mixed results. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate. Question: Why did Mendel use pea plants in his experiments? What minimal rate of infusion is maintained for a to keep open TKO IV infusion? What biological concept was Mendel studying when he crossed pea plants many times over many generations? When Mendel measured two or more traits (eg, height and color) in an experiment he found that each trait was transmitted independently. What is the stamen of a flower? Principle of Paired Factors: A character is represented in an organism (diploid) by at least two factors. Genes are responsible for the expression of traits. He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. hope it's helpful for you . Inheritance involves the passing of discrete units of inheritance, or genes, from parents to offspring. In 1856, he began a decade-long research pursuit involving inheritance patterns in honeybees and plants, ultimately settling on pea plants as his primary model system (a system with convenient characteristics that is used to study a specific biological phenomenon to gain understanding to be applied to other systems).
