4 0

Answer:

Restriction enzyme

Explanation:

  • Gel electrophoresis is a process or a technique in which fragments of DNA  are separated in terms of their sizes.
  • <em><u>The restriction enzyme is mixed with a DNA sample before the process. The restriction enzyme cut DNA at specific points into fragments which can then be separated based on their sizes on an agarose gel.</u></em>
  • When current is applied to the gel DNA move towards the positively charged electrode since DNA is negatively charged, with shorter fragments migrating faster through the gel in comparison with large fragments.

Answer:

The situation in which some individuals have greater reproductive success than other individuals in a population. Along with variation and heritability, it is one of the three conditions necessary for evolution by natural selection.

There are so many factors that contributed to this over time, reproductive success differs and it could be attributed to hereditary and variation as well. Most often, the hereditary plays the most role out of all as the viability of both eggs and sperms could have been inherited from parents or being affected as a result of environmental factor or nutrition or other factors.

For instance, if one has a rhesus factor of negative and went ahead to marry another male counterpart with negative rhesus factor, this sedomly leads to miscarriage which could have been controlled had it been they were thoroughly counseled. Furthermore, physical factor such as accident could damage one spermatical vessicles that houses the sperm cells which render such an individual to be unable to donate a viable sperm cell for reproduction.

Those with high rate of reproductive success thrives as result of having many offspring which increases their chances of having more offspring than those with little success rate.
