What most likely explains the recovery of live S strain cells from a mouse injected with heat-killed S strain mixed with live R strain cells?
a. The S strain was revived by the presence of the host's immune system.
b. The R strain picked up the S strain DNA, enabling it to produce a capsule.
c. The R strain cells picked up the capsules from the S strain cells.
d. The S strain fused with the R strain, making it resistant.
Ans: b. The R strain picked up the S strain DNA, enabling it to produce a capsule.

In humans, normal skin pigmentation is influenced by a dominant gene (C), which allows
pigmentation to develop. All individuals who are homozygous for the recessive allele (c) are unable to produce an enzyme needed for melanin formation and are therefore referred to as albino. Two normal parents produce an albino child. What are the chances that the next child will be an albino? What will be an ideal response?
