This type of allele is most likely to increase in frequency in a population.
a) beneficial recessive allele
b) harmful recessive allele
c) beneficial dominant allele
d) harmful dominant allele
What is c) a beneficial dominant allele.
A beneficial allele produces a phenotype with increased fitness.
A beneficial dominant allele is more likely than a beneficial recessive allele to increase in frequency in a population because an individual with just one copy will tend to reproduce more. At low frequency, it is very unlikely for any individual to exhibit the recessive phenotype (even if it is beneficial) because it is very unlikely for any individual to have the two copies (to be homozygous recessive) necessary to exhibit the phenotype.
