[iii] He found that F1 progeny was all tall plants.

[iv] He selfed the (hybrid) plants if F1 progeny.

[v] He found that in F2 progeny there were tall as well as short plants.

[vi] The three quarter plants were tall and one quarter was short.

Assume that an organism exists in which crossing over does not occur, but that all other processes associated with meiosis occur
MakcuM [25]

Answer:

Option (e).

Explanation:

Meiosis may be defined as the process of cell division in which a single parent cell divides into four daughter cells. The chromosome number reduces to half in meiosis.

Crossing over is the process of exchange of genetic material between the homologous chromosomes of the non-sister chromatids. Crossing over will bring variation in the gametes. Hence, the absence of crossing over results in the formation of gametes with less genetic variation.

Thus, the correct answer is option (e).
