Ainat [17]

Answer:

The correct answer is-

F1 -  AaBb (lacerate)

F2 - A_B_; A_bb; and aaB_ (lacerate)

     - aabb (normal)

2. Two genes, with a dominant allele at either or both loci.

Explanation:

The given information gives THE following data:

Dominant: Lancerate leaves - AABB

Recessive: normal leaves - aabb

F1 has - all Lacerated leaves - AaBb

F2 by selfing F1:

         AB               Ab         aB         ab

AB    AABB        AABb      AaBB    AaBb

Ab     AABb       AAbb      AaBb     Aabb

aB     AaBB       AaBb       aaBB     aaBb

ab     AaBb       Aabb       aaBb      aabb

Here, 15/16 = lacerate which is 0.94 which is equal to the value of lacerate given in the question - 249/265 = 0.94

And normal 1/16 = 0.062 is almost same as 16/265 = 0.060

Thus, the genotypes of -

F1 -  AaBb (lacerate)

F2 - A_B_; A_bb; and aaB_ (lacerate)

     - aabb (normal)
