thread - like dna strands that carry genetic information are referred to as
cortisol.
chromosomes.
gametes.
glia.
you read a research study describing how some disease is more commonly found in both adopted children and their adopted parents than in adopted children and their biological parents. what can you likely infer about this disease?
it is more related to environmental than genetic factors.
gene mapping would likely reveal a single gene responsible for the disease.
it has a strong hereditary (genetic) component.
the disease is polygenic.

Explanation:

For the first question: Cortisol is a hormone, gametes are reproductive cells, glia are brain support cells; chromosomes are thread-like DNA strands carrying genetic info.
For the second question: A stronger correlation with adoptive (non-genetic) parents means environmental factors play a larger role than genetic ones. Single-gene/strong hereditary/polygenic would link closer to biological parents.

Answer:

1. B. chromosomes.
2. A. It is more related to environmental than genetic factors.
