Because the pigments have higher possibility to survive because of their color of skin/fur they could have an easier camouflage and the albinos cant survive that easy.
Recessive allele.
It is controlled by a recessive allele.
An allele present in all members of a population
The frequency for the mutant cystic fibrosis allele among Caucasians is 0.025, while the frequency of the normal allele is 0.975.
Think frequent. More of the allele in the populations gene pool and there is a change in the alleles frequency. Some goes for less of the allele.
because the recessive allele is still present in heterozygous individuals. these individuals have one dominant allele and so show the dominant phenotype but they are capable of producing offspring with the recessive condition
its not anything.
Random change in allele frequency is called genetic drift.
To determine how allele frequency changes
Allele frequency.
A minor allele is the allele that has the least frequency among all the alleles in a given population and this has to be greater than 5%.
Yes, the ratios of genotypes for a specific trait can change if allele frequency changes.
