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. The egg and the sperm have a aploid chromosome number

4. Sexual reproduction of cells - Has 2 division cells - makes 2 complete sets

Crossing over y/n
duplication of chromosomes y/n
Meiosis
5. A zygote has a _________ chromosome number
aploid
Meiosis
Half
diploid
6. Forms when one sperm cell gains an egg cell fertilize and make complete set
Reproductive organs
zygote
diploid

7. Gives variations in species because of overcrossing Meiosis is a bit different because there something called crossing - over happens with the DNA. This crossing over is an exchange of genes. The genes are mixed up - not resulting in a perfect duplic
