Heredity Basics
The passing of traits from parents to offspring
What is Heredity
This type of trait (allele) is always expressed if present
What is dominant/dominant trait
Is eye color inherited or acquired
What is inherited
What do we call the basic units of heredity
What are genes
What shape is DNA
The total number of pairs of chromosomes that humans typically have
What is 23 pairs
If two parents are both "bb" for blue eyes, what color will their child’s eyes be
What is Blue eyes
Is the ability to speak a language inherited or acquired
What is acquired
What percent of DNA do you get from each parent
What is 50%
What is the section of DNA that codes for a trait
What is a gene
The part of the cell that contains everything we have talked about?
What is the nucleus
In a cross between "TT" and "Tt," what percent of the offspring will be tall if "T" is dominant
What is 100%
What’s the main difference between inherited and acquired traits
What is inherited traits come from DNA; acquired traits are learned or developed
If a mother is a carrier for color blindness (X-linked) and the father is not color blind, what are the chances of their son being color blind

Is a scar inherited or acquired
What is acquired
A characteristic passed from parent to offspring
What is a trait
