Genetics and Natural Selection

For 2 points. What is the term used for transmission of the traits from one generation to the next generation?

This term refers to the variation in a population or species. (2points)

The study of science which deals with the mechanisms responsible for similarities and differences among closely related species. (2 Points)

This type of variation refers the differences in the genome, it may be due to structure or number of chromosomes present in the cells or difference in the genetic constituents of the chromosomes. Skin, hair, eye colour, height are some of the genotypic variations in animals.

• Somatic variations

• Genotypic variations

• Genetic variation

• Gene sequencing

These variation are not hereditary. These are not due to changes in the alleles or chromosomes. These are due to various factors such as nutrition, climate and due to other social interactions.

• Somatic Variation

• Genotypic Variation

• Gene Sequence

• Adaptation

Known as the father of genetics. He was the first to show the inheritance pattern of traits from one generation to the next generation.
