The '2n' number of chromosomes in a human female represents:
How many chromosomes are there in meiocytes of human beings? (Write in numbers)
Law of independent assortment can be explained by monohybrid cross.

Gender of a child is determined by the male partner of the couple.
The DNA fragments can be isolated using the technique called Agarose gel electrophoresis.
Observe the table in which size of different DNA fragments are given and answer the question:
| DNA | A | B | C |
| Size (in base pairs) | 700 | 1500 | 3000 |
