Embryos have the genes of _____.
1.the female parent
2.both parents
3.the male parent
4.neither parent
Answer:
2. Both parents
Explanation:
there are three copies of one particular chromosome instead of the normal two (one from each parent)
14. How many pairs of chromosomes do humans have? Why do you think there are pairs?
Answer:
1. Humans have 23 pairs of chromosomes--22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y. Each cell in the human body contains 23 pairs of such chromosomes; hence our diploid number is 46, the number 'singularity' is 23.
2. This is because our chromosomes exist in matching pairs - with one chromosome of each being inherited from the biological parent.
