Genetics Answers

You are a researcher in the Plant Biodiversity Department. Three types of mango leave isolated from Gunung Ledang, Lembah Pantai and Kota Bharu were sent to your department/laboratory. Suggest the most appropriate method to study the expression levels of steroid-related genes (steroid gene A, steroid gene B, and steroid gene C) in all of the samples. Justify why the suggested method is the best approach.

A breeder wishes to produce more prize- winning dogs from his 2 - year - old male schnauzer. What are his options? Which method would produce the most exact copy? Also, what is the difference between artificial insemination and reproductive cloning? Does artificial insemination produce identical copies?

When resolving taxonomic uncertainty what are the three most widely used frameworks in determining Evolutionary Significant Units (ESU)?

Context: multigene families

Explain the evolutionary significance of the P450 cytochrome family and the amylase family and indicate how they provide flexibility to organisms.

Context: multigene families

Describe the beta globin gene family and indicate how it provides developmental flexibility.

A group of genetics students mix two auxotrophic strains of bacteria: one is leu+ trp+ his− met− and the other is leu− trp− his+ met+. After mixing the two strains, they plate the bacteria on minimal medium and observe a few prototrophic colonies (leu+ trp+ his+ met+). They assume that some gene transfer has taken place between the two strains. How can they determine whether the transfer of genes is due to conjugation, transduction, or transformation?
