Answer:
PROBLEM 1
Most nonprimate mammals exhibit dichromacy, with color vision based on just two kinds of visual pigments. These animals do not have full color vision. Although the mechanism of gene inactivation is slightly different in Old and New World primates, the evolution of trichromacy enabled these mammals to see a technicolor world of flowers, fruits and insects. This is somewhat analogous to the evolution of high resolution color monitors from the drab monochrome green and amber progenitors. One obvious advantage of trichromacy is being able to clearly distinguish the subtle shades of ripening fruit from surrounding vegetation. Color vision in higher primates is similar to the the mixing of red, green and blue pixels to generate a full spectrum of color in computer monitors. The following table shows 216 color combinations produced from three colors using a six character hexadecimal HTML code. People with color blindness would have difficulties in distinguishing all of these shades of color.
PROBLEM 2
The genotype of the carrier female is X
. The genotype of the male with normal blood clotting is x.
If a carrier female marries a male having normal blood clotting factor, then the daughters will have genotype
(normal) and
(carrier). All the daughters will have normal clotting of blood but half of them will be carriers. The genotype of the sons will be X
(normal) and (haemophilic). Half the sons will be haemophilic while remaining will have normal clotting of blood. From the above cross, it is evident that the pattern of inheritance of haemophilic is criss-cross as the gene of the disorder is transmitted from grandfather to grandson through his daughter.
PROBLEM 3
One of the easiest ways to calculate the mathematical probability of inheriting a specific trait was invented by an early 20th century English geneticist named Reginald Punnett click this icon to hear the preceding name pronounced. His technique employs what we now call a Punnett square. This is a simple graphical way of discovering all of the potential combinations of genotypes that can occur in children, given the genotypes of their parents. It also shows us the odds of each of the offspring genotypes occurring.
