Explanation:
did you complete the quiz?
The Sickle cell disease is a genetically inherited deformed cell. These cells are deformed into crescent shaped moons. This is serious and can lead to blood clots. Since these cells are deformed, they usually can’t fit in the capillaries aka tubes that carry blood throughout your body. These sells can block the entrances to the capillaries and cause blood flow to stop being transferred from one area of the body to another.
<span>Chromosomes can increase genetic diversity by the way they are replicated. Since chromosomes are paired, and sperm and egg cells have only 1 of each pair, few sperm and egg cell wil have identical chromosomes. For humans, with 23 chromosome pairs, the number of possible combination of chromosomes for any child is over 8 million. That means the chance of any 2 siblings (who are not identical twins) having the same chromosomes from both parents is less than 1 in 8 million. Add to that the possibility of chromosomal crossover during the production of sperm or egg cells, and the number of different gene combinations in any child becomes staggering. If a frog, for example, lays a few thousand eggs, chances are that all of them will have different chromosomes within their cells. That may be why natural selection has favored organisms with dozens of pairs of chromosomes. Organisms with lots of chromosomes can maintain a high level of diversity within the population. Since genetically diverse species are more resistant to disease, it is not difficult to understand many different lineages have converged upon the same solution of having dozens of chromosomes.</span>
I would say true...because if an animal population grows and they eat then what ever they eat i am sure would go down in population..
