What does it mean that an allele is "dominant" as opposed to being "recessive?" Whether an allele is dominant or recessive depends on: a. Whether it is inherited from the mother or the father. b. How common the allele is, relative to other alleles. c. Whether or not it is on a ...
What is an example of a population in biology?Biological Population:In social science the term 'population' refers to all the people who live in a given area (usually a nation or city). In biology, however, it has a different connotation used to better understand ecological health. ...
One is purely green dominant, expressed as “GG,” each “G” representing an allele; the other is completely blue recessive, “gg,” which means this parent is actually blue in color. Since any offspring they have gets one allele from each parent, all of their offspring would have colorat...
What is meant by an allele? An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. ... Alleles contribute to the organism's phenotype, which is the outward appearance of the organ...
Genetic drift has been shown to play an important role in the formation of new species because over time, it leads to the fixation of certain alleles or genotypes in a population. Fixation refers to the case where one allele among several remains the only one in a population after the loss...
What is genotyping? Genotyping Overview Genotyping is the process of determining the DNA sequence, called a genotype, at positions within the genome of an individual. Sequence variations can be used as markers in linkage and association studies to determine genes relevant to specific traits....
Random mating prevents change in allele frequency(as described in Hardy Weinberg law) in a population when other evolutionary forces are not acting; though that does not happen in nature. Why is random mating important to Hardy Weinberg?

(a) What is the difference between mortality and reproductive rates? (b) Do they equally make an impact on population growth? (c) If yes or no, why? What is the relationship between population genetics and natural selection? What is a change in allele frequency of a species or population...
When many different cells in the same organ have different somatic mutations, it is called a mosaic. This can be differences in allele frequency or copy number. Using SNP gene array chips, mosaics can be detected if over 5% of the cells have them. PCR (polymerase chain reaction) or mass ...
