Today, I have a biology class. We learnt about mutation. We must do a discussion about it. This is a part of our discussion.
Description:
Mutation is a change in genetic material so that the expression (phenotype) change. Mutation can occur in base pair, one segment of DNA, or even on the chromosome.
Various kinds of Mutation:
1. Based on the types of cells
a. Somatic Mutation, is a mutation occurs in somatic cells. This mutation is only inherited / derived in somatic cells. For example: mutations in skin cells that causes skin cancer.
b. Germinal mutations, are mutation that occur in cells of gametes (sperm or ovum). Mutation is inherited in subsequent generation. For example: kinds of disabilities and illnesses adrift down the chromosome X or Y chromosome.
2. Based on the number / extent of genetic material that have mutation
a. Gene mutation (point mutations), is a mutation that occurs due to a change in one base pair of DNA a gene.
b. Chromosome mutations (aberrations), are mutation that caused the changes in the number and structure of chromosome.

Hey, I am checking this blog using the phone and this appears to be kind of odd. Thought you'd wish to know. This is a great write-up nevertheless, did not mess that up.
