A. Alice carried the recessive allele
The answer to this question would be: 2^23
When the gene is dividing, the chromosome pair, which was made by 2 single chromosome, will be divided into two single haploid chromosomes. That means there is two kind of possibilities for each chromosome. If there are 23 chromosomes then it will be 2^23 possibilities

A mutation that involves one or a few nucleotides is called
a) mutagen
b) inversion
c) point mutation
d) translocation
Answer:
c) point mutation
Explanation:
When only one or a few nucleotides of a gene are changed by mutation, this is called a point mutation. A point mutation can add one additional nucleotide to the wild type gene or may delete or substitute a nucleotide from it. For example, if a wild type gene sequence is "ATATATATA", then the addition of "C" at the position 4 will change it into "ATACTATATA". This addition of new nucleotide is called point mutation since only one nucleotide is added to the gene. Point mutations can cause serious genetic disorders such as sickle cell anemia.
