Discuss the genetic background existing between meiosis and sexual
reproduction and we are also asked to find a disorder with specific
inheritance pattern resulting from mutation.

Eukaryotic cells can divide by mitosis or meiosis. In humans, mitosis produces new cells for
growth and repair. And, meiosis produces sex cells (gametes), called sperm and eggs. Changes
or mutations in genes in sex cells can be inherited by human offspring. Genetic variation in a
population of organisms is good; however, sometimes mutations can be harmful or cause
Briefly, answer the following questions:
1. How do meiosis and sexual reproduction (fertilization) produce offspring that differ
genetically from the parents?
2. Describe one example of a human disorder that is inherited and also describe the
specific inheritance pattern. For this example, pick disorders that result from mutations
in DNA or chromosome number rather than examples such as a genetic tendency for a
disorder such as cancer.
Genes are the integral part of the human life and play a huge role in determining the sex of the
human when it undergoes the process of reproduction especially meiosis and fertilization. The
difference in the genes in each individual determines the characteristics of the of each person
