.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. It means chromosomes are paired. One of each chromosome in a pair originates from the father and one from the mother. They affect the same trait - but don't necessarily cause the same expression of the trait.
