As alleles become fixed, there is an overall decline in heterozygosity as each population become homozygous for one or the other of the alleles.
The dominant allele overpowers a recessive allele, therefore when the two are combined (heterozygous) the phenotype of the organism becomes whatever the dominant allele represents.
Allele frequency is stable
If color is 100 percent black then then genetic variation is 1
According to mendel's law of segregation, what happens to chromosomes during meiosis is that, allele pairs do separate leaving each and every cell with a single allele for each trait.
The genotype for free ear lobes is usually represented as FF or Ff, where F stands for the dominant allele for free ear lobes. The genotype for fixed ear lobes is typically represented as ff, where f stands for the recessive allele for fixed ear lobes.

If this happens, the dominant allele masks the recessive allele.
The dominant allele overpowers a recessive allele, therefore when the two are combined (heterozygous) the phenotype of the organism becomes whatever the dominant allele represents.
In a heterozygous offspring, the recessive allele is present but not expressed because the dominant allele masks its effects.
The genotype is said to be heterozygous and the dominant trait will be expressed in the individual.
As the population size increases, the probability that an allele will fix in the population also increases. This is because larger populations provide more opportunities for the allele to spread and become fixed.
