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; atp and nadph;

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
