Q. 9 - Biology

Question

In agriculture, polyploid crops (like coffee, strawberries,or bananas) tend to produce ____.

a. more uniformity

b. more variety

c. larger yields

d. smaller yields

Step-by-Step Solution

Answer

The Correct answer is c.

Step. 1 Introduction

Polyploid plants have 3 or even more identical pairs of chromosomes. A genomic multiplication occurrence caused the rise in chromosome number in such plants.

Step. 2 Explanation for correct answer

Polyploidy occurs when the amount of identical homologous chromosomes exceeds the usual ploidy limit.

Step. 3 Explanation for incorrect answer

Option a. Gene uniformity occurs only when both gametes have the identical gene form.

Option b. This does not increase diversity since the situation exists only due to existence of more sets of paired pairs.

Option d. This situation is prevalent in plants, and it promotes adaptation by producing evolutionary flexibility.
