what was found to be on chromosomes by the scientist in question 3?
genes
dirt
extra dna

Explanation:

• Question 2: Meiosis is a type of cell division that reduces the chromosome number by half. It is crucial for sexual reproduction as it produces gametes (sperm and egg cells) with half the number of chromosomes of the parent cell. When fertilization occurs (sperm and egg fuse), the full chromosome number is restored in the zygote.
• Question 3: Walter Sutton studied grasshopper sperm and egg cells. He is known for the chromosome theory of inheritance, which proposed that genes are located on chromosomes.
• Question 4: Genes are the units of heredity. Sutton's work (along with others) led to the understanding that genes are located on chromosomes. Chromosomes carry genetic information in the form of DNA, and genes are specific segments of DNA on chromosomes that code for particular traits.

Answer:

• Question 2: half
• Question 3: Walter Sutton
• Question 4: genes
