Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The diploid number of chromosomes for guinea pigs is 64. How many chromosomes will be found in their gametes?
A
16
B
32
C
64
D
128
Explanation: 

Detailed explanation-1: -Meiosis will result in the production of two cells, each with 16 chromosomes. 3. The total number of chromosomes in a guinea pig cell after meiosis is 46.

Detailed explanation-2: -The chromosome number of the Guinea pig fetal fibroblast cells was 2n = 64, comprising 62 autosomal and 2 sex chromosomes (Figure 4).

Detailed explanation-3: -Summarizing the guinea pig karyotype description based on published data and presented here we can conclude that: the diploid chromosome number is 2n = 64 and the fundamental number of chromosomal arms is FN = 92.

Detailed explanation-4: -A diploid cell has two complete sets of chromosomes. Most cells in humans are diploid, comprising 23 chromosome pairs, so 46 chromosomes in total.

Detailed explanation-5: -The gametes of human cells are haploid, from the Greek haplos, meaning “single.” This term implies that each gamete contains half of the 46 chromosomes-23 chromosomes in humans.
