The correct answer is option B, that is, a person with type O blood has two recessive genes.
An illustration of a trait determined by a single gene is blood type. Each human exhibits two copies of the gene for blood type on chromosome pair number 9. One of the copy is inherited from the father and the other one is inherited from the mother. An individual's blood type is determined by which allele he or she inherits from the parents.
In case of blood type O, O is a recessive allele. If an A or B is inherited along with the O gene, the A or B gene decides the blood type of an individual. An individual is considered to have type O only if that person inherits two O genes, that is, a person with type O blood exhibits two recessive genes.
B interest rates are not just the same as we do not like that we have a new account and a dollar on our own account so you don’t want it for the first one and then
Answer:
Ancient landmasses
Explanation:
The same fossils being found in widely separate areas can help scientists infer the geography of the continents of that time.
For example: Africa and South America used to be connected during the Permian Period.
Scientists can confirm this because both continents are home to similar fossils.
