In the fictional hobbit, there exist 5 alleles of the foot size gene:
Fl-F5. Each allele is dominant over an allele with a higher
number. For example F3 is dominant over F4, and Fis
dominant over F5 F5 is recessive to all other Falleles, and
results in a hobbled hobbit. This is usually a lethal phenotype.
How does the Fs allele stay in the gene pool?
a All heterozygous genotypes with an F5 allele are
carriers.
b All F5 homozygous individuals are selected for by
natural selection.
Ć The Fof5 hobbit is selected for by natural
selection.
d all of the above
