Explain why different gametes produced by the same person can have different combinations of alleles for genes that are located

on two different chromosomes
Biology

Gnoma [55]3 years ago

Because we all have 23 pairs of chromosomes, one half from your Dad, one half from your Mum. Therefore, you will have different combinations of genes in your chromosomes from being born. However, when gametes are formed from Meiosis, the chromosomes are split apart, then form a new cell before being split apart yet again. Since 4 cells are created from Meiosis, all 4 gametes will be completely different. Hope this answered it.

Answer:

  • One spermatogonium produces 4 spermatids FALSE. One primary spermatocyte produces 4 spermatids.

Explanation:

Germ cells are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through mitosis, they originate more sexual cells, but through meiosis, they produce gametes -sperm and egg cells-. This process is known as gametogenesis.

Gametes´destiny is to merge during fecundation, and a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell and suffers successive mitosis to form the new organism.

Spermatogenesis is the process of production and maturation of sperm cells. Spermatogonia are the masculine diploid germ cells, carrying 46 chromosomes. These germ cells suffer mitosis to reproduce. Some of them stay as spermatogonia, and some others become primary spermatocytes, which are in charge of gamete production. Primary spermatocytes are also diploid cells, meaning that they still carry 46 chromosomes.

Each primary spermatocyte replicates its genetic material and then goes through meiosis I to produce two daughter haploid cells called secondary spermatocytes, each of them carrying 23 chromosomes. Each secondary spermatocyte will produce two other haploid daughter cells by meiosis II.

The total result from the two cellular divisions of each primary spermatocyte is four haploid daughter cells called spermatids.

During spermiogenesis, spermatids mature into spermatozoa or sperm cells. Each sperm cell characterizes by being composed of a head, midpiece, and tail.

  • DNA replicates once, but cells divide twice TRUE
  • The products are spermatozoa that each have a head, midpiece, and tail TRUE  
  • Spermatids containing 23 chromosomes (1n) are produced TRUE
  • One spermatogonium produces 4 spermatids FALSE. One primary spermatocyte produces 4 spermatids.
  • Genetically diverse spermatids are created TRUE

The instructions for making new copies of a virus are (1 point)
IgorLugansk [536]

Correct answer: C). Coded in either DNA or RNA.

The instructions for making the new copies of the virus are coded either by the RNA or the DNA. The genetic material of the viruses are either the DNA or the RNA and they are known to contain the instructions for making the new viral copies. Before the viral replication, the virus gets into the cell. The viral copies of the virus are known to infect the host.

Hence, the correct answer would be option C.
