Which two processes that occur during the formation of gametes contribute to increasing diversity within a populations gene pool
yanalaym [24]

Answer:

1) Crossing over

2) Independent assortment.

Explanation:

Gametes are formed resulting from the process of meiosis where the gametes get half of the original number of chromosomes. One phenomenon that happens during the prophase 1 of Meiosis and leads to the genetic diversification is crossing over. In this process , Here, homologous chromosomes pair up and exchange information present on genes from one another. When information is exchanged, it leads to the diversity of genetic data.

The second way of increasing genetic diversity is independent assortment that takes place during metaphase 1. In this process chromosomes from both father and mother cells align on equatorial plate of the cell in an independent manner. This means that some gamete can have 1 of many different chromosomal combinations.

This reshuffling of chromosomes during independent assortment enhances the genetic diversity of any organism and this also explains why kids of same parents can look or behave very different.

Hope it help!

Why is the sarcoplasmic reticulum. How does it aid in the stimulation of muscle contraction?
Mandarinka [93]
Activation of muscle contraction could be a speedy event that's initiated by electrical activity within the surface membrane and transversal (T) tubules. This can be followed by unharness of metal<span> from the inner membrane system, the sarcoplasmic reticulum.

A class of proteins that eukaryotes use to turn genes on and off by allowing transcription to ouccur or blocking it are called ?
arsen [322]
I think you're talking about histones. Histones are proteins found in eukayotic cell nuclei. Histones are what DNA wrap around so it fits inside the nucleus and helps with the formation of chromosomes.
