A man heterozygous for blood type A marries a woman heterozygous for blood type B. The chance that their first child will have type O blood is??

Answers

Answer 1
Answer:

The chance that their first child will have type O blood is 25% since the genotypes of offsprings are I^(a)i, I^(b)i , I^(b)i , ii.

What is a blood group?

An allele is a particular form of genetic information that can be found in our DNA at a particular spot on a certain chromosome. This form of genetic information is known as an allele. IA, IB, and i are the three distinct alleles that can determine a person's blood type. I is the most common. These three alleles can be referred to as A (for IA), B (for IB), and O for the sake of simplicity (for i).

Therefore, when a man heterozygous for blood type A marries a woman heterozygous for blood type B the chances that their first child will have type O blood is 25% since the genotypes of offsprings are I^(a)i, I^(b)i , I^(b)i , ii.

Emperor penguins huddle together during the Antarctic winter months. Once a penguin reaches the interior of the huddle heA)remains on the interior to stay warm
B) moves back to the exterior to allow another individual the chance to warm
C)moves back to the exterior to find food
D)remains on the interior waiting for mate to
bring food to the interior
E) help digest food

Answers

Emperor Penguins huddle together during the winter without eating - they have eaten before the winter and they live of their saved fat during this time - so the answer won't have to do with food. The correct answer is B) - they move back to the exterior (or are pushed by other penguins) - only like this can all the penguins survive the winter, by cooperation, rather than being selfish.

True/false: individuals with familial Down syndrome are trisomic and have 47 chromosomes

Answers

Final answer:

True, individuals with familial Down Syndrome are trisomic and have 47 chromosomes. This occurs when there's an extra copy of chromosome 21 as a result of a parent carrying a rearranged chromosome, or translocation.

Explanation:

True. Individuals with familial Down Syndrome are indeed trisomic, which means they have an extra copy of a certain chromosome. In the case of Down Syndrome, there's an extra copy of chromosome 21, resulting in a total of 47 chromosomes instead of the usual 46. People inherit this condition through familial Down Syndrome when one parent carries a rearranged chromosome, referred to as a translocation. In this type of Down syndrome, there are three copies (i.e., trisomic) of chromosome 21.
