We have always thought that Rudolph the red-nosed
reindeer was a one of a kind. However in
the remote reaches of Scandinavia, there has been
numerous citings of red-nosed reindeer.
A recent study by population genetics reviled that red-nosed reindeers
occur 3 out every 100 reindeer. Further
DNA analysis has shown that the red-nosed gene is recessively inherited.
- What is the frequency of the recessive allele? Dominant allele?
- What is the percentage of the population that does not
have red-noses, but could pass on this gene to its offspring?
- What’s the probability that two non-red nosed
reindeer may meet and have red-nosed offspring?
During the holiday season the dominantly inherited gene
for overspending often times kicks into high gear. Roughly 80% of shoppers in The Shops at Mission
Viejo have the overspending gene.
- What percentage of the population is recessive for
the overspending gene?
What percentage of the shoppers at The Shops at Mission
Viejo are homozygous dominant for this overspending gene?
What percentage is heterozygous for this overspending
- What is the frequency of both the dominant and
Elf is one of the taller elves, but he’s not
alone. The allele for increased height
is recessively inherited and actually occurs in about 5% of the elf population
working in Santa’s workshop.
- What is the frequency of this recessive allele?
