Features & Traits
This is a general characteristic of a species, like "eye color."
What is a feature?
These molecules are responsible for the actual "work" of creating a trait.
What are proteins?
This term refers to a specific form of a gene that provides instructions for a protein.
What is an allele (or gene version)?
Offspring receive this many copies of every gene—one from each parent.
What is two?
True or False: Traits are produced by proteins, which are controlled by genes.
What is True?
This is a specific variation of a feature, such as "thick, white fur."
What is a trait?
This part of a protein molecule determines exactly how it functions.
What is its structure/shape?
This is the primary function or "job" of a gene.
What is acting as an instruction manual for building proteins?
This is where genes are physically located inside the nucleus.
What are chromosomes?
True or False: Every cell in an organism (except reproductive cells) has the same instructions.
What is True?
If two organisms show the same trait, they likely have these in common.
What are protein molecules?
A mutation in a gene would most likely lead to a change in this.
What is the shape or function of a protein?
An organism is called this if it has two different alleles for a gene.
What is heterozygous?
This is why siblings can look different even though they have the same parents.
What is inheriting different combinations of alleles?
True or False: An organism can have three different alleles for a single gene.
What is False? (They only have two alleles because they have two parents).
Between "Hair color" and "Blue Eyes," this one is the feature.
What is Hair color?
The instructions for making proteins are found here.
What are genes?
An organism is called this if it has two identical versions of a gene.
What is homozygous?
In sexual reproduction, this is the exact percentage of DNA received from each parent.
What is 50%?
True or False: Different alleles always result in the same protein shapes.
What is False? (Different alleles usually mean different shapes).
This must be present for an offspring to show a specific trait.
What is at least one gene version that codes for the proteins of that trait?
The two main things about a protein molecule that determine how it functions.
What are structure and shape?
(DAILY DOUBLE) An organism that has two identical versions of a gene is classified as this.
What is homozygous?
(DAILY DOUBLE) This is the specific location where genes are found within a cell
What are chromosomes (inside the nucleus)?
True or False: If two organisms have different alleles, they will always have the same protein shapes.
What is False?
