Heredity is known as the phenomena of inheritance of traits or features of parents to offspring's or progeny. A trait is any characteristic that is transferred from parent to offspring. ... Without heredity, there can be no evolution either. Genetics is that branch of biology which deals with heredity and variation.

Revision notes on Heredity and Evolution

The study of heredity and variation is known as genetics. Heredity is defined as transmission of characteristics from parents to offspring's. ... There are two types of variation- somatic variation and gametic variation. Somatic variation occurs in the somatic cell of the body

What is meant by heredity and evolution?

Through heredity, variations between individuals can accumulate and cause species to evolve by natural selection. The study of heredity in biology is genetics

Types of Heredity

Genetic variations such as mutations are responsible for creating alleles. Differences in DNA base pairs can also change function or phenotype. Mendel's conclusions about alleles became the basis for two major laws of inheritance: the law of segregation and the law of independent assortment.



What are the rules of heredity?

Mendel stated that each individual has two alleles for each trait, one from each parent. Thus, he formed the “first rule”, the Law of Segregation, which states individuals possess two alleles and a parent passes only one allele to his/her offspring
