If two mutations that affect the same trait differently are incorporated in a single organism, is there a specific kind of genetic interaction that is most likely or is it completely random? A:Genes are the basic units of heredity and can be found in almost all living things. Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes.

It is caused by a defective, recessive allele. 3 1.Describe the ways that gene number or gene position on a chromosome, might be altered? if the allele frequency does not change over time then: it is likely that the allele does not offer any fitness advantage and the population is large. In the example above, we went through all nine individuals in the population and looked at their copies of the flower color gene. C) The effects of differences in frequencies for different alleles are more pronounced with small numbers of zygotes. Therefore, the allele frequency will not be stable and the HW equilibrium will no longer be applicable. You have two types of garden gnomes in a population.
