Answer: One parent is IAi and the other parent is IBi
Explanation: As this trait is codominant, the child can inherited IA, IB or i.
Tina has type O, which means she is ii and her sister is AB, so her genotype is IAIB. Now, to have a child with a recessive trait both parents has to carry at least one allele for the recessive, i. Rosa is type AB which means she had to have inherited one allele IA from one of her parents and the other IB from the other parent. Thus, one parent is IAi and the other is IBi.

In mitosis, the nucleus divides followed by the cytoplasm dividing, resulting in two cells. ... If the cell cycle is not carefully controlled, it can cause a disease called cancer, which causes cell division to happen too fast. A tumor can result from this kind of growth.
