Why are diploid cells abbreviated 2n and haploid cells abbreviated 1n​
Ganezh [65]

Answer:

Diploid cells abbreviated 2n and haploid cells abbreviated 1n​ because 'n' represents number of chromosome present in the cell. In haploid cells the number of chromosome is half in number while in diploid cells the number of chromosome is double so that's why haploid is abbreviated as 1n and diploid is abbreviated as 2n.

Diploid cells are present in body cells while haploid cells are found in sex cells.

Drag each tile to the correct location on the chart. What are the pros and cons of sexual and asexual reproduction?
levacccp [35]

Answer:

Sexual reproduction:

Pros: leads to greater genetic variation.

Cons: requires more time and energy.

Asexual reproduction:

Pros: Does not require finding a mate.

Cons: Produce less genetic variation.

Explanation:

Sexual reproduction is a type of reproduction in higher organisms, in which new individuals are formed by combining genetic information from two different types (sexes) of individuals.

Advantage: Sexual reproduction leads to higher genetic variation due to recombination between genetic material of female and male gamete during meiosis.

Disadvantage: Sexual reproduction is a time and energy consuming process as it needs interaction between mates and organisms which are produced sexually require more time for development.

Asexual reproduction involves formation of new organisms from a single parent organism without gamete fusion.

Advantage: Asexual reproduction requires less time and energy as it does not require finding a mate.

Disadvantage: Asexual reproduction produces less genetic variations as it involves only parent organisms (no mixing of genetic information) and the only source of variations are random mutations.
