I have trouble with biology but I think the answer is recessive
Answer:
Blood types: AB, A, B, and O in ratio 1:1:1:1
Explanation:
The ABO blood group system is employed in Humans. The alleles for blood type A (A) and blood type B (B) are dominant over the allele for blood type O (O).
If a man who is heterozygous for blood type A (AO) marries a woman who is heterozygous for blood type B (BO), the following gametes will be produced by each parent:
AO - A and O
BO - B and O
Using these gametes in a punnet square, the following proportions of offsprings will be produced:
Blood type AB - 1/4
Blood type A - 1/4
Blood type B - 1/4
Blood type O - 1/4
Answer:
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
