Question

The genotype of a seeded pea plant is denoted RR and that

of wrinkled seeded plant rr. When cross between them

occurs.

(a)What will be the phenotype expected in F1, generation?

(b)Give the percentage of wrinkled seeded plants if F1, plant

are self pollinated.

(c)In which ratio do you find RR, rr and Rr in F2

generation.​

Answer 1

Answer:

Explanation:

A)-PHENOTYPE WILL BE ALL ROUND SEEDED PEAS.

(B)- 25 % - IN F-2 GENERATION IF F-1 ARE SELF POLLINATED WILL BE WRINKLED.

(C)- GENOTYPIC RATIO OF RR TO Rr will be 1:2 in F-2 PROGENY

THIS IS SUFFICIENT BUT IF THE SAME QUESTION COMES FOR 5 MARKS EVEN THE CROSS SHOULD BE MENTIONED, WORKOUT OF PUNNETT SQUARE SHOULD ALSO BE SHOWN.....

HOPE THIS HELPS YOU
