1. does a mom or dad ever give more DNA to a baby than other parent? why? 2. how does meiosis reduce the amount of DNA in a sperm and eggs by half?

3. how does every sperm and every egg get to become genetically unique(different)?

4. how does fertilization create genetically unique kids from the same two parents ?

5. how can the 2 same parent have kids with different traits?​

Explanation: 1. If a baby is male, it got more DNA from its mother because the X chromosome is larger than the Y chromosome.

2. Meiosis results in a double cell division producing four haploid cells.

3. during meiosis, some DNA is exchanged between the single strands (recombination).

4,5. The haploid gametes have different combinations of the parental DNA, ending with a zygote that includes two effectively unique gene combinations

answer: 2

explanation:

yes
