In animals polypoidy is rarely practiced as _______________

(b) Increase in size is not appreciable

(c) It is often sterile

(d) Animal cells are resistant to colchicine

This question was addressed to me in quiz.

Query is from Chromosomal Abnormalities : Euploidy in portion Chromosomal Basis of Inheritance of Cytogenetics

Answer 1

Correct choice is (b) Increase in size is not appreciable

For explanation I would say: The other options being true, in animals there is a more strict regulation of gene product formation than in the case of plants. In animals with an increase in cell size there would be a decrease in cell number keeping the ultimate animal sizes same. It is thus not profitable at all.
