Question 8
The origin of new alleles at a gene locus is the result of A. migration. B. mutation. C. recombination. D. independent assortment.
Worked Solution & Example Answer:The origin of new alleles at a gene locus is the result of A - VCE - SSCE Biology - Question 8 - 2002 - Paper 1
Step 1
B. mutation.
Answer
The origin of new alleles at a gene locus is primarily due to mutations. Mutations are changes in the DNA sequence that can result in new alleles being formed. These alterations may occur due to various factors such as errors in DNA replication, environmental influences, or chemical exposure. While migration, recombination, and independent assortment play roles in the genetic variation within populations, it is mutations that directly lead to the creation of new alleles.
