1
Q

What are chromosomes?

A

Chromosomes are threadlike strands of DNA (deoxyribonucleic acid) molecules that carry genetic information.

2
Q

What are genes?

A

Genes are DNA segments that serve as the key functional units in hereditary transmission

3
Q

What are polygenic traits?

A

Polygenic traits, or characteristics that
are influenced by more than one pair of genes.

4
Q

What are family studies?

A

In family studies, researchers assess hereditary influence by examining blood relatives to see how much they resemble one another on a specific trait.

5
Q

What are twin studies?

A

In twin studies, researchers assess hereditary influence by comparing the resemblance of
identical twins and fraternal twins with respect to a trait.

6
Q

What are adoption studies?

A

Adoption studies assess hereditary influence by examining the resemblance between adopted children and both their biological and their adoptive parents.

7
Q

What is genetic mapping?

A

Genetic mapping is the process of determining the location and chemical sequence of specific genes on specific chromosomes.

8
Q

What is epigenetics?

A

Epigenetics is the study of heritable changes in gene expression that do not involve
modifications to the DNA sequence.
