_____________________

1. what genetic analysis tool do we use to analyze non - disjunctions?

_____________________

1. what other types of chromosomal mutations exist?
2. looking at the genetic analysis to the right, what 2 things can be

determined?

1. explain the differences in the cells below. (be sure to discuss how they

are made)
sperm cell

1. matching: match the vocab word to its definition.

___ gene a. the smallest living unit
___ gamete b. the substance of that carries your traits
___ offspring c. another word for child or baby
___ chromosome d. dna that is coiled tightly (humans have 23 pairs)
___ dna e. sex cells
___ cell f. a piece of dna that codes for a protein

Explanation:

Question 10 Matching

• Gene: A gene is a segment of DNA that contains the instructions for making a protein, so it matches F.
• Gamete: Gametes are sex cells (sperm and egg) that fuse during fertilization, so it matches E.
• Offspring: Offspring refers to a child or baby (the result of reproduction), so it matches C.
• Chromosome: Chromosomes are tightly coiled DNA structures, and humans have 23 pairs, so it matches D.
• DNA: DNA is the molecule that carries genetic traits (the genetic material), so it matches B.
• Cell: A cell is the smallest living unit of an organism, so it matches A.

Answer:

Gene: F. A piece of DNA that codes for a protein
Gamete: E. Sex cells
Offspring: C. Another word for child or baby
Chromosome: D. DNA that is coiled tightly (humans have 23 pairs)
DNA: B. The substance of that carries your traits
Cell: A. The smallest living unit
