Answer:
DNA replication is described as semi-conservative.
Explanation:
DNA replication is described as semi-conservative because each double helix formed comprises one strand from the helix from which it was copied and a new strand. That is, the replication of one helix results into two new copies of which each contains one of the original double stranded helix from which it was synthesized.
Answer:
2) 25%
Explanation:
To answer this question, we can draw a punnett square.
Father has type Ao, so he has one A allele, and one o allele.
Mother is type Bo, so she has one B allele, and one o allele.
_ | A | o
B | AB | Bo
o | Ao | oo
25% AB, 25% Bo, 25%, Ao, 25% oo
Since blood type o is recessive it will only be expressed phenotypically when not masked by a dominant allele which only occurs when the genotype is oo. Therefore the answer is 2) 25%.
