Answer 1

Answer:

Mendel's principles of inheritance

Gregor Mendel was the first person to describe the manner in which traits are passed on from one generation to the next (and sometimes skip generations). Through his breeding experiments with pea plants, Mendel established three principles of inheritance that described the transmission of genetic traits before genes were even discovered. Mendel's insights greatly expanded scientists' understanding of genetic inheritance, and they also led to the development of new experimental methods.

One of the central conclusions Mendel reached after studying and breeding multiple generations of pea plants was the idea that "[you cannot] draw from the external resemblances [any] conclusions as to [the plants'] internal nature." Today, scientists use the word "phenotype" to refer to what Mendel termed an organism's "external resemblance," and the word "genotype" to refer to what Mendel termed an organism's "internal nature." Thus, to restate Mendel's conclusion in modern terms, an organism's genotype cannot be inferred by simply observing its phenotype. Indeed, Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations. Mendel thus wondered how organisms preserved the "elementen" (or hereditary material) associated with these traits in the intervening generation, when the traits were hidden from view.

Explanation:

Answer 2

Mendel proposed three rules for inheritance.

Explanation:

1. Every inherited trait is determined by the pair of gene. The  genes  from parents are randomly separated by the sex cells that consists of the pair of gene.

2. The genes are sorted separated for the purpose of inheritance. The inheritance of one kind of trait is independent on another kind of trait.

3. The organisms with the alternate forms of the gene will express their form of trait that is dominant.Mendel proposed three rules for inheritance.
