What did he experiment on? - Correct Answers ✅Gregor Mendel; Peas What are Mendel's 4 Laws? - Correct Answers ✅1) The Law
of Independent Unit Characters: Characters (Ex. height, color,
etc.) are inherited separately as units.
2) The Law of Segregation: Body cells and primordial germ
cells contain pairs of such unit characters and that when gametes are produced, each gamete receives only one member of such pair
3) The Law of Dominance: In every individual there is a pair
of determining factors (genes) for each unit character, one from each parent, if these factors are different (heterozygous), one character (the dominant) appears in the organism, the other (recessive); the recessive character can appear in the organism only when the dominant is absent.
4) The Law of Independent Assortment: Any one pair of
characters is inherited independently, regardless of transmission of other traits. 1 / 3
