Heart disease has been widely known for being genetic, but whether it is due from the environment or genetic has yet to be established. Some heart disease symptoms are chest pain, palpitations, pressure in the chest, and discomfort in the back and jaw. Although heart disease can be deadly, there is treatments available. Firstly, you could get a heart transplant or you can get a surgery to remove what has caused the disease like lead for example. There is a wide variety of medicines available to help those with the disease as well.
Answer:
The correct answers would be maintain chromosome number through generations and cause genetic variations by recombination.
In Meiosis a cell divides into four daughter cells all of which have half the number of chromosomes present in a parent cell.
It helps in the formation of gametes in sexually reproducing organisms.
These gametes (one from father and one from mother) fuse together to form a zygote. It re-established the chromosomal number as that of the parent.
In absence of meiosis, the chromosomal number would have doubled after each generation.
In addition, the meiosis also increases the genetic variation among the population with the help of crossing over which occurs during the pachytene stage of prophase I.
During this event, genetic information is exchanged between the non-sister chromatids of the homologous chromosomes. It produces a new combinations of genes that are different from either parent.
<em>For example,</em>
<em> consider a mountain whose summit is 5,000 feet (1,500 m) in elevation, but somewhere on the way up, the trail goes back down 250 feet (76 m). ... </em>
<em>If one hikes over five hills of 100 vertical feet each, the cumulative elevation gain is 5 × (100 feet (30 m)) = 500 feet (150 m).</em>
