If it was a double heterozygote, then aabb will be AaAaBbBb. It will form 4 types of gametes since we have Aa, Bb.  It will have aB, AB, ab, Ab.

An individual will form  only 2 type of gametes, Aa, Bb.

In comparison with the renal cortex, fluid in the proximal tubule is hyperosmotic.
ArbitrLikvidat [17]

The proximal tubule fluid is more hyperosmotic than the renal cortex, but this does not influence what is causing the acid-base disruption.

<h3>How does hyperosmotic work?</h3>

In the extracellular space, the first drop in temperature results in the formation of crystals, which creates a hyperosmotic environment that draws water out of the cells and causes them to contract. Organelles & biological membranes are damaged as a result of inner crystal formation as the temperature drops.

<h3>What transpires inside a hyperosmotic environment to a cell?</h3>

A cell submerged in a 10% dextrose hyperosmotic , osmotic pressure solution would initially lose area as water departs and then start gaining proportion as glucose is delivered through into cell as moisture follow by osmosis. This is because water crosses cell surfaces more quickly than solutes do.

professor190 [17]

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.
