Question

You are studying a population of dragonflies looking at 2 alleles labeled X1 and X2. In your new season of fieldwork you find 53 of the 472 individuals you examine have a new allele, X3. It seems very unlikely that a new mutation would be found in that many individuals. A. (1 pt.) What seems like the most likely hypothesis to explain the presence of this new allele in your study population? B. (2 pts.) How would you test this hypothesis in the field? Outline how you would test the hypothesis, but do not go into a step by step detail.

Explanation / Answer

A. we can say that new allele is generated due to the mutation in previous alleles. beautician can be generated by the error in replication, due to environmental factor, chemical factors and radiation factors.

all factors leads to change in the DNA sequence either one or more nucleotides call does mutation. change in DNA leads to change in phenotype. in the population in new gene or DNA is formed by the mutation and favoured by the natural selection process.

B. we can check the frequency of allele by allele frequency hypothesis.

Hardy weinberg equation is applicable to check this hypothesis in which we have multiple conditions.

various other hypothesis are available to check the change in allele frequency or allele.

the best and molecular way to check the formation of new allele by Sequencing of DNA. through this we we can check the change in DNA sequence very accurately.
