Question

Please explain Somatic variations.
And difference between somatic and genetic variations.​

Answer 1

Human somatic variations are mutations that occur in somatic cells both at early stages of development and in adult cells. ... Occurrence of this phenomenon not only can result in major phenotypic changes but also reveal the expression of otherwise lethal genetic mutations.

Genetic variation refers to diversity in gene frequencies. Genetic variation can refer to differences between individuals or to differences between populations. Mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well.

hope it helps u mate have a good day ✌️

Answer 2

Explanation:

Somatic variation : Human somatic variations are mutations that occur in somatic cells both in early stages of development and in adult cells .Occurence of this phenomenon or only can result in major phenotypic changes but also reveal the expression of otherwise lethal genetic mutations.

Difference between Somatic and Genetic variations :

Somatic Variations :

• Somatic Variations is the genetic variation occuring in any of the cells except sex cells.
• Somatic cells (any of the body cells except germ cells) Location of somatic cells
• Non-Inheritable.Variation dies with the death of the individual.
• They are not significant since they are not coming from parents.
• They are harmless.
• Their rate of mutation is high.
• They are not related to evolution.
• They have acquired variation.

Genetic Variations :

• Germinal variation is the genetic variation occuring in the germ cells.
• Germ cells Location of the cells
• They are heritable.
• They are significant.
• They are harmful.
• Their rate of mutation is less.
• They are related to evolution.
• They have Blastogenic variation.
