Answer:
The possible blood types their children could have are A or 0.
Explanation:
The I gene determines the blood type of a person. I is the dominant allele, while i is the recessive allele.
- IA dominant over i. The person presents A type of antigens.
- IB dominant over i. The person presents B type of antigens.
- IA and IB are codominant. The person presents both types of antigens, A and B.
- i is the recessive allele. The person does not present any antigen.
Cross: a person who is blood type O with a person who is blood type A
Parental) ii x IA-
Gametes) i i IA -
Punnet Square) IA -
i IAi -i
i IAi -i
The - symbol represents the possibility of either IA allele or i allele. This is, the parental with blood type A might have the genotype IAIA or IAi
F1) 2/4 = 1/2 IAi
2/4 = 1/2 -i (-i could be either IAi or ii, depending on the genotype of the parental with blood type A)
- <u>Option 1</u>: ii x IAIA
F1) 100% IAi (The whole progeny will have blood type A)
- <u>Option 2</u>: ii x IAi
F1) 50% IAi (Half of the progeny will have blood type A)
50% ii (Halfa of the progeny will have blood type 0)
The possible blood types their children could have are A or 0.

Biodiversity is the different life forms and animals that exist on earth and the biosphere is where all of those life forms and animals live. <span />
Cells with nucleus and organelles are called eukaryotic cells and are under the domain Eukarya. They also have specialized organelles that are not found in other domains like Bacteria and Archaea.
