Determine the correct reason for which Mendel chose pea plant for hybridization experiments (a) Pea plants have long generation time (b) There are very few contrasting characters in pea plantis (e) Chances of mixing of other characters from outside is low as peu flowers are self-pollinating (d) Cross-pollinating the pen flowers artificially is not at all possible
Answers
Answer
(a) Mendel selected garden pea plant for his experiments because of the following characteristics:
(i) The flowers of this plant are bisexual.
(ii) They are self-pollinating, and thus, self and cross pollination can easily be performed.
(iii) The different physical characteristics were easy to recognise and study.
(iv) They have a shorter life span and are the plants are easier to maintain.
(b) According to Mendel's law of independent assortment, during the inheritance of two or more characters, the assortment of individual traits takes place independently during gamete formation. Thus each allele of a pair segregates independently and each gamete formed contains one allele of that trait. This law is inapplicable for linked genes.
Answer:
pea plant have long germination time
