Isn't it amazing that children can look like their parents and brothers and sisters but different from each other? This course will teach you about heredity. Heredity is the sum of all biological processes by which particular traits are transmitted from parents to their children. By the end of this course, you will have studied heredity in animals, plants, bacteria, and viruses, and looked at the theory behind the Hardy-Weinberg Principle.

Description

Gregor Mendel is the founder of the science of genetics and is known as the father of genetics. He identified many of the rules of heredity which determine how traits are passed through generations of living things, and that traits could skip a generation. This course will introduce you to Gregor Mendel and his works on heredity. You will also explore every different combination of all the genes using the Punnett square.

The Hardy–Weinberg Equilibrium (HWE) states that allele and genotype frequencies in a population will not change from generation to generation where there is an absence of other evolutionary influences or disturbing factors. This course will discuss the Hardy-Weinberg equilibrium and give you examples to understand the principle better. You will also study sex-linked traits, which is an important category of genetic linkage that has to do with the X and Y sex chromosomes.

Heredity is the genetic transmission of characteristics from parent to offspring. By the end of this course, you will have learned how some of these characteristics can have a physical manifestation like hair color or color blindness, why some traits are passed on while others skip generations, and why some traits form part of our physical makeup while others are carried but never physically expressed. So, check out the course today and start learning all this and more!
