Concept explainers
a.
To determine: The chances of the child to have blood group A when his mother is type A and father is type AB.
Introduction: The human blood group system is an example of codominance where the alleles for the two antigens A and B are equally dominant. This means that when the two antigens A and B are present the blood group is AB while in the absence of both the antigens the blood group is O.

Human Heredity: Principles and Issues (MindTap Course List)
- Suppose a woman has four sons, and two are colorblind but have normal blood clotting and two have hemophilia but normal color vision. What is the probable genotype of the woman? b. Suppose this woman (later on) had a son with normal vision and normal blood clotting. How can this be explained?arrow_forwardSuppose a woman who is a carrier (XNXN)marries a man who is colorblind (XnY). Is there any chance that they will have a male child with a normal color vision? What are the possible phenotypes? 大 A. No chance, 2 female carrier and 2 males colorblind B. Yes, 1 female carrier, 1 female color blind, 1 male with normal color vision and 1 male colorblind C. Yes, 1 female colorblind and 2 males with normal vision and 1 male colorblind D. Yes, 2 males with normal color vision and 2 females carrierarrow_forward50 Mendel formulated his Law of Segregation after he had: Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a studied F1 offspring b studied F2 offspring C produced mutations identified chromosomesarrow_forward
- In Figure 3-9,a. identify the diploid nuclei.b. identify which part of the figure illustrates Mendel’sfirst law.arrow_forwardRed hair is recessive to dark hair. If red-headed Jack fathers a child with red-headed Lisa, what are the chances that their children will have red hair? Show you work using a Punnett square.arrow_forwardA cross occurs between a chicken with white feathers and a chicken with black feathers. This results with offspring with some black feathers and some white feathers. What type of inheritance is this? a. incomplete dominance b. complete dominance c. codominance d. blended dominancearrow_forward
- If a man with blood type AB marries a woman with blood type B whose father was type O, what phenotypes could their children have? a. A onlyb. A, AB, B, and Oc. AB onlyd. A, AB, and Be. O onlyarrow_forwardRalnh has type B blood and his wife Rachel has type A blood. They are very shocked to hear that their baby has type O blood, and think that a switch might have been made at the hospital. Can this baby be theirs? O A. Yes, if both parents are homozygous recessive O B. Yes, if Ralph is homozygous and Rachel is heterozygous O C. No, this baby is not theirs. D. Yes, if both parents are heterozygous for their blood typesarrow_forwardBaldness is a phenomenon where individuals lose hair as they grow older. As an X-linked recessive gene, what instances do females manifest this trait? a. heterozygous recessive b. heterozygous dominant c. homozygous recessive d. homozygous dominantarrow_forward
- How similar is your genetic information to that of your parents? A. You have a set of genes similar to those your parents and inherited from their parents B. For each gene, One of your alleles is from one parent and the other one is from the other parent C. Depending on how much crossing over happens you can have a lot of one parents genetic information and little of the other parents genetic information D. You can the same genetic information as each of your parents just as much as halfarrow_forwardshow a cross between a woman with blood type o and a man who is heterozygous blood type b. Using mendels rules. What is the percent chance that the child has blood type o?arrow_forwardWhat is the likelihood that a parent with Type AB blood would have a child with Type O blood?a. 50%b. 25%c. 0%d. This can’t be determined without knowing the blood type of the other parent.arrow_forward
