Question

question 7

during spermatogenesis, what is the end result of meiosis?

one sperm cell with 23 chromosomes
two sperm cells with 46 chromosomes each
four sperm cells with 23 chromosomes each
one sperm cell with 46 chromosomes

Explanation:

Analyze the process of spermatogenesis

$$ \text{Primary spermatocyte } (2n = 46) \xrightarrow{\text{Meiosis I}} 2 \times \text{Secondary spermatocytes } (n = 23) $$

$$ 2 \times \text{Secondary spermatocytes } (n = 23) \xrightarrow{\text{Meiosis II}} 4 \times \text{Spermatids } (n = 23) $$

Determine the chromosome count and cell number

$$ \text{Total functional gametes produced} = 4 $$

$$ \text{Chromosome number per cell} = 23 \quad (\text{haploid}) $$

Match with the given options

The end result is four sperm cells (spermatids that mature into spermatozoa) with 23 chromosomes each.

Answer:

• One sperm cell with 23 chromosomes
• Two sperm cells with 46 chromosomes each
• Four sperm cells with 23 chromosomes each (Correct answer)
• One sperm cell with 46 chromosomes
