Answer:
The wechsler intelligence scale for children (WISC) is a good indicator of innate "genetic" ability for children of six to sixteen years old.
Explanation:
Wechsler Intelligence Scale for Children (WISC) is basically a system of testing IQ of children from six to sixteen years old. This testing was created by David Wechsler, who stated that intelligence is a global quality and it should be reflected in children's verbal as well as non-verbal abilities.
This testing system is used by schools for several purposes:
• To evaluate the performance of kids during placement process.
• It is also used to evaluate abilities of dis-abled children or deferentially able children.
• IQ scores from WISC can be used to diagnose the problems of the children such as mental re-tardation or some specific learning dis-ability. It can also be used to determine the problems of the children who face hyperactivity or attention deficiency.
• In addition, the test can also diagnose brain related and neuro-psychological disorder.
Point to remember:
The WISC system is not useful to determine the extreme form of intelligence like IQ below 40 and above 160. Wechsler himself focused on this point many times that test is not adequate for children with IQs of below 70 or above 130. Despite of this fact, people use this test to determine the intelligence of deferentially able children who usually have IQ above 130 that is not very appropriate thing.

Answer:
The genotypes of the two parents: normal head shape (HH) and Bart head shape (hh)
The genotypes in the F1 generation= Hh
The phenotypes present in the F1 generation= All normal head shape
Explanation:
Let's assume that the allele "H" is responsible for the normal head shape while the allele "h" gives Bart head shape. According to the given information, both the parents are homozygous. The genotype of the parent with normal head shape would be "HH" while that of the one with Bart head shape would be "hh". Since the normal head shape is dominant, all the F1 hybrid progeny would exhibit "normal head shape".
The phase contrast microscope uses out-of-phase and in-phase light rays that produce contrast areas allowing scientists to detect even a minute number of protein molecules and focus on the minute internal structures of a particle.

That would be : adenine, thymine, guanine, and cytosine.
