a. 1: 1

b. 2: 1

c. 3: 1

d. 4: 1

Conducting a monohybrid cross of F1 generation plants, the recessive trait reappears in F2 plants in a ratio of 3.1.

A monohybrid is a hybrid that is heterozygous with respect to a specified gene.

The correct answer between all the choices given is the third choice or letter C. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

The correct answer for the blank is-

C. 3:1

Monohybrid cross is a genetic cross between two organisms, which are having pure homozygous genotype for one contrasting character/ trait ( such as between tall and dwarf height of pea plant).

This means that parents are pure breeding (TT and tt for tall and dwarf respectively) for a contrasting trait.

Parents - TT and tt  will produce all offspring with the genotype Tt ( tall, as T is a dominant allele that depicts tall plant height and masks the dwarf plant height when present with t allele, which is for dwarf height).

When plants of F1 generation ( that is Tt and Tt) are crossed, they will produce offspring in the ration 3: 1 ( tall: dwarf) in F2 generation.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
