Question

A diagram shows a potato producing new tubers. Buds on the parent plant grow into stems that grow downwards called stolons. The end of each stolon develop in to new tuber.
1) Give two pieces of evidence which show that this is an asexual method of reproduction.

2) Explain why all the new tubers will be genetically identical.

​

Answer 1

Answer/Explanation:

Asexual reproduction is a type of reproduction in which new organisms that are identical are formed form a parent without the fusion of male and female gametes and do not require fertilization. Offspring formed are usually identical genetically, and are referred to as clones of the parent. Usually, only one parent is involved.

1. Two pieces of evidence that shows the potato growing is an asexual method of reproduction are:

i. Only one parent is involved

ii. The new tubers are identical (clones of the parent)

2. Reasons Why the new tubers will be genetically identical:

i. They grow from 1 parent by asexual reproduction

ii. No mixing of male and female gametes, so no exchange of genes takes place
