Expert Solution & Answer

Summary Introduction

To explain: The genetic disadvantages of cloning done by Somatic Cell Nuclear Transfer (SCNT).

Introduction: In sexual reproduction, genetic information from both the parents is combined together to produce the offspring. A cell having two sets of chromosomes is known as diploid whereas, a cell having a single copy of chromosomes is known as haploid. Sperms are the gametes produced by males and eggs are the gamete produces by females, these gametes fuse together to form a zygote.

Explanation of Solution

An offspring which is the identical copy of the parent is known as its clone. Asexual reproduction is a method to produce clones naturally. Clones can also be produced artificially in the laboratories. Somatic cell nuclear transfer is a method of producing clones artificially. In the somatic cell, nuclear transfer nucleus from a somatic cell is implanted into an enucleated oocyte to produce an embryo. Therefore, SCNT can be used for cloning experiments. Dolly the sheep was the first clone produced by the technique.

Following are the genetic disadvantages of cloning done by SCNT to preserve highly endangered animals:

As the clones are identically similar to the parents, genetic diversity will decrease in producing a clone through SCNT and as a resulting susceptibility to a particular genetic disease carried by the parent will increase in the next generation.
Producing clones will also increase homozygosity and decrease the chances of evolution.
Incomplete reprogramming of the cells can also produce abnormal phenotypes.

Thus, SCNT has certain genetic disadvantages such as production of abnormal phenotypes, an increase in homozygosity, an increase in susceptibility to genetic diseases.
