Answer:
ABO blood type B
Explanation:
The blood sample only contains B as a surface antigen (simplified as the sugars clinging to the blood embedded halfway inside) making any other blood type unviable. B would be the only option.
Answer:
15/16 or 93.75%
Explanation:
<em>The proportion of the offspring of the cross expected to be red would be 15/16 or an equivalence of 93.75%.</em>
Red fruit color is conditioned by the presence of A_, B_ or A_B_ alleles. In the absence of both dominant alleles, the condition is white. AaBb was crossed with AaBb.
AaBb x AaBb
Progeny' Genotype Phenotype
1 AABB red
2 AABb red
2 AaBB red
4 AaBb red
1 AAbb red
2 Aabb red
1 aaBB red
2 aaBb red
1 aabb white
Hence, the proportion of the offspring that are expected to be red is 15/16 or 93.75%.
<em>See the attached image for the Punnet's square analysis of the cross.</em>
1: B
2:D
Those are the answers!
