Question

prior knowledge:

1. what do you already know about the difference between dominant and recessive traits? or sex - linked and autosomal traits?

case studies: read each case study and answer the questions.
case study 1: cystic fibrosis (adapted from: about cystic fibrosis images from: http://archive.industry.gov.au/biotechnologyonline.gov.au/popups/img_cffamilytree.html)
cystic fibrosis is a progressive, genetic disease that causes persistent lung infections and limits the ability to breathe over time. in people with cf, a defective gene causes a thick, sticky buildup of mucus in the lungs, pancreas, and other organs. in the lungs, the mucus clogs the airways and traps bacteria leading to

Explanation:

The question is about prior knowledge of genetic traits (dominant/recessive, sex - linked/autosomal) and a case study on Cystic Fibrosis (a genetic disease). The subfield of Natural Science that deals with the study of genes, heredity, and genetic diseases is Biology. So the most appropriate subfield is Biology.

Answer:

Biology
