Question

Q28.Mendel crossed a pea plant having round green seeds with pea plant having
wrinkled yellow seeds. (3)
(i) What type of cross is it?
(ii) What type of plant are obtained in F1 generation?
(iii) In F2 generation, the phenotype ratio is 9:3::3:1,
State the rule of inheritance of traits as observed by Mendel​

Answer 1

Answer:

(i) first generation ( Mono hybrid)

(ii) In F1 generation all dominant plants are obtained i.e all progeny are round and green

(iii) Mendel's rule of inheritance was that all F1 generation express dominant traits and only in F2 there is possibility of recessive traits.

Answer 2

Answer:

Mendel stated that each individual has two alleles for each trait, one from each parent. Thus, he formed the “first rule”, the Law of Segregation, which states individuals possess two alleles and a parent passes only one allele to his/her offspring.
