Traits and Genes (MS-LS3-2 LT 2, 3, & 4)

What is the difference between an inherited trait and an acquired trait?

• An acquired trait is determined before you are born, an inherited trait is not.

• An inherited trait is passed through sexual reproduction, while an acquired trait is not.

• An inherited trait can be changed during an organism’s lifetime, while an acquired trait cannot.

• An acquired trait is passed through sexual reproduction, while an inherited trait is passed through asexual reproduction.

Genes are _______________________________.

• Made up of chromosomes.

• Made up of proteins.

• Sections of DNA, that provide instructions for a specific trait.

• Sections of DNA, that provide instruction to make chromosomes.

Chromosomes come as _________________________________.

• pairs, one from each parent

• pairs, from only one parent

• as individual sections of DNA

• as individual sections from genes

Where can DNA be found?

• In every cell in the body.

• Only in skin cells.

• Only in sex cells.

• Each cell contains DNA, but only the part that it needs.

Offspring will be genetically different from their parents because

• of a sexual reproduction.

• their genetic information is identical to both parents.

• they only receive genetic information from one parent.

• they receive genetic information from both parents.

In humans, when sperm or egg cells are formed, the DNA is rearranged in a way so that no sperm or egg cells are the same. During sexual reproduction, a random sperm cell fertilizes a random egg cell. What effect might this have on the traits of the offspring?

• The offspring would look identical to each other because they would inherit the traits from the same two parents.

• The offspring would look different from each other because they would acquire different traits from their environment.

• The offspring would look identical to each other because they would acquire the traits from the same environment.

• The offspring would look different from each other because they would inherit different traits from random sperm and egg cells.

What genotype would a child have to have in order to be left handed?  R is dominant for right handed.

• rr
• Rr
• RR
