Answer: Jack has the genotype Bo; Jill is AB; Jack's mother is OO.
Explanation: In the ABO blood type, the alleles A and B are dominant over O. However, the allele A is co-dominant with the allele B. That means an individual can have a genotype AB, which is Jill's case: her blood type has the two allele. For Jack's mother, her blood type is O. As O is recessive, her genotype will be OO, indicating the recessiveness. For Jack, his mother is recessive, so he will have genotype heterozygous for blood type B, which means BO.
The correct answer is B. The iris would get smaller, the pupil would get bigger.
Explanation
The iris is the name by which the colored part of the eye is known, it is located between the cornea and the lens. In the central part of the iris, there is a round opening known as the pupil. The relationship between these two parts of the eye is very important to sight because between them they control the amount of light that enters the eye. This occurs when the eye is exposed to a high amount of light, the iris muscles make the pupil smaller and the iris larger, limiting light entry into the eye. When the eye is exposed to low amounts of light or darkness, the iris becomes smaller and the pupil enlarges, allowing more light to enter. According to the above, the correct answer is B. the iris would get smaller, the pupil would get bigger. Because it describes the behavior of the iris and the pupil when going from a bright room to a dark room.
