Heyaa!!!
❤️When two organisms reproduce through sexual reproduction, the offspring display traits from both parents. For example, one’s hair color is often similar to their parents’ or similar to another relative. This is because of inheritance, or the passing on of traits, which was discovered by Gregor Mendel in the 1800s.Before Mendel’s realization, farmers used these principles without realizing it in a process called artificial selection, or human-caused changes in a population.They selected plants with desirable traits and bred them together to create offspring with a mix of those same favorable attributes.
In fact, Mendel worked with pea plants to come up with his laws of inheritance. Mendel chose plants with differences in a trait such as stem length, pea shape, or flower color. He noticed that if he mixed two plants with opposite traits, such as wrinkled and round pea shape, then all of their offspring would be round.However, when he bred this offspring with itself, he noticed that on average 1/4 of the second generation of plants expressed the “wrinkled” trait, which had supposedly disappeared during the previous generation. From this observation, he realized that genes—or the units of heredity—are made up of different combinations of the parents’ genes.
