Answer:
Phenotypes of offsprings: Type A, Type B
Explanation:
This question involves a single gene for blood group in humans. The ABO blood group system consist of three alleles: A, B, and O. A and B are dominant over O but co-dominant to one another.
If a woman with type O blood (OO) has a child with a male with type AB blood (AB) i.e OO × AB, the following gametes will be produced by each parent:
OO - O
AB - A and B
Using these gametes in a punnet square (see attached image), the offsprings with the following genotyoes will be produced: AO (2), BO (2)
AO - phenotypically type A
BO - phenotypically type B
Hence, a type A and type B blood group offsprings will be produced.
Answer:
you should always wash your hands regularly and avoidance of shaking hands
It makes sense that increasing the rate of plastics recycling is helpful for eliminating waste. Think about it, when something can be reused, then it should be. Recycling allows this to happen and prevents landfills from being filled too quickly.
B. X-linked. When traits are more common in males, this means that it is linked to the X chromosome and a dominant trait. In order for the trait to show, it would need one dominant gene. Since males only have one X chromosome, this makes the change of a gene being dominant 50/50. The daughters do not have it because they have the recessive form of the gene on both of their X chromosomes.
