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.
Hey there!
<em>Every </em> living organism is made up of cells. The number of cells can range from one to more than a million! Cells are what make up our bodies, and if it weren't for cells we might not be here!
Hope this helps!

Answer:
c. Light
Explanation;
In 1779 Jan Ingenhousz found that how the plants exchange CO2 and Oxygen. He discovered the photosynthesis.
He showed that the green parts of plants release oxygen bubbles in the presence of light.
He also showed that the plants release the CO2 during the night and the amount of CO2 released during the night is less than the amount of oxygen released during the daylight. So plants also use some mass from soil.
Answer:
It is the temperature difference in the water can cause the currents in the ocean to vary.
