Question

Answer these questions if POSSIBLE!!! (Biology) 100 Points!! ONLY ANSWER IF U KNOW THE QUESTION!!!

1. What indicates that evolution is taking place in a population? Use the word alleles in your "answer".

2. What are three sources of genetic variation?

3. How does the range of phenotypes for single-gene traits differ from the range for polygenic traits?

Answer 1

1 - The change in gene pool (change in alleles) which means that the individuals are changing and devolping new characteristics along with new species.

2 - Sex, mutation and gene flow are the three sources of genetic variation.

3 - Single-gene traits can only have 2 different phenotypes while polygenic traits can have many phenotypes.

Hope it helped,
