The sperm cell would have twice the DNA as the muscle cell.

|
The sperm cell would have half as much DNA as the muscle cell.

|
The sperm cell and muscle cell would contain the same amount of DNA.

The muscle cell would have four times the DNA as the sperm cell..

Detailed explanation-1: -Q. How would the DNA in a horse muscle cell compare with the DNA in a horse sperm cell? The sperm cell would have twice the DNA as the muscle cell.
Detailed explanation-2: -We use “c” to represent the DNA content in a cell, and “n” to represent the number of complete sets of chromosomes. In a gamete (i.e. sperm or egg), the amount of DNA is 1c, and the number of chromosomes is 1n. Upon fertilization, both the DNA content and the number of chromosomes doubles to 2c and 2n, respectively.
Detailed explanation-3: -Explanation: The cells produced at the end of meiosis cell division have half the number of chromosomes (termed as Haploid), so they will have half the number of chromosomes but same DNA as that of the parent cell as DNA divides and makes a copy of the parent cell DNA.
Detailed explanation-4: -They line up in pairs during a critical period in meiosis. If we look at the gametes from a horse and a donkey, we see that a horse gamete contains 32 chromosomes and a donkey gamete contains 31 chromosomes.
Detailed explanation-5: -In females, the process of meiosis is called oogenesis, since it produces oocytes and ultimately yields mature ova(eggs). The male counterpart is spermatogenesis, the production of sperm.
