Respuesta :

There will be 34 chromosomes in each gamete.

If a horse cell undergoes meiosis, there will be 32 chromosomes in each gamete.

What is meiosis?

  • In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).
  • Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).
  • The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state.
  • Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.
  • Meiosis uses a two-step division mechanism to achieve these goals.
  • During the initial round of cell division, known as meiosis I, homologue pairs split apart.
  • Sister chromatids split apart during meiosis II, the second round.
