Which of the following is a source of genetic variation in sexually-reproducing organisms? a-meiosis b-mitosis c- translation d- all of these

Answer : The correct answer is -

A-meiosis.

Meiosis is a type of cell division (a reductional cell division) that occurs during the process of formation of gametes particularly in sexually reproducing organisms.

During prophase of meiosis I, crossing over between homologous chromosomes takes place, resulting in the genetic diversity in new chromosome that come in the gametes.

Apart from this, when gametes from two parents fuse, new genetic combination is produced in the resulting zygote.

Thus, meiosis is a source of genetic variation in case of sexually reproducing organisms.

this is a good question! i'll do some research and come back when i have the answer!

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
