Answer:
Yes.
Probability of such child = 1/2 or 50%
Explanation:
According to the question, below are the genotypes and phenotypes possibilities:
aa = normal vision & no headache
Aa = normal vision & no headache
AA = blindness & headache
Male Female
Aa aa
Possible genotypes of progeny: Aa Aa aa aa
So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.
Mathematical expression is as under:
2/4 = 1/2 that means 50% progeny.

<span>In a desert, water is in scarce supply, so excreting water would be a bad thing and might cause the death of any animal that does so due to dehydration.
There can be several different mechanisms to overcome this. One would be to have the bladder discharge urine into the large intestine where the water can then be reabsorbed into the body while the urea in the urine is passed out along with other solid wastes produced by digestion. Some other methods of conserving water would be for the kidneys to extract more water from the urine leaving the urine fairly concentrated. Also animals may behave in manners that conserve water such as staying in the shade during the day and only being active at night.</span>

The cerebral cortex can be described as the thin layer of the brain that covers the outer part of the cerebrum. This layer is also made up of tightly packed neurons and can also be described as the wrinkly, outermost layer that surrounds the brain (the surface of the brain is not smooth but consist of folded bulges that is called gyri which create deep fissures called sulci). This increases the surface area and also the amount of information that is processed. It is also referred to as the gray matter and is also responsible for higher thought processes including speech and decision making
Yes, if the immune system is strong, it is capable of fight off an illness with the help of the white blood cells (leukocytes).
