C) Viruses need a host to survive
The probability of the offspring of a heterozygous father and homzygous mother having five fingers is 50%.
<h3>How to calculate genotype of a cross?</h3>
According to this question, a gene coding for the number of fingers in humans is involved. The allele for six fingers (F) is the dominant trait while the allele for five fingers (f) is the recessive trait.
If a cross between a heterozygous father that posseses a genotype of Ff and a homzygous mother that posseses a genotype of ff, the following offsprings will be produced:
This shows that the probability of the offspring of a heterozygous father and homzygous mother having five fingers is ½ (50%).

The nitrogenous bases in DNA are adenine, guanine, thymine, and cytosine.
The nitrogenous bases in RNA are adenine, guanine, uracil, and cytosine.
So the base in RNA that is different than in DNA is uracil.
