What best explains how meiosis contributes to genetic variation in a species?
Meiosis allows for crossing over chromosomes , resulting in new gene combinations.
Meiosis will contain daughter cells that will contain identical chromosomes.
Meiosis reduces the number of mutations in a organism.
Meiosis results in offspring that contains alleles from only one parent gamete

The correct explanation is "Meiosis allows for crossing over chromosomes, resulting in new gene combinations."
To understand how meiosis contributes to genetic variation in a species, it's important to know that meiosis is a specialized type of cell division that produces haploid cells (gametes) with half the number of chromosomes as the parent cell. It involves two rounds of division, resulting in four daughter cells.
During meiosis, there is a process called crossing over or recombination that occurs in prophase I. This is when homologous chromosomes pair up and exchange genetic material. Portions of the chromosomes break off and switch places with corresponding sections of the other chromosome, resulting in new combinations of genes. This genetic exchange enhances genetic diversity in the offspring.
The other options listed (meiosis resulting in daughter cells with identical chromosomes, reducing mutations, and having offspring with alleles from only one parent gamete) do not accurately explain how meiosis contributes to genetic variation. Daughter cells from meiosis contain unique combinations of genetic material, resulting in genetic diversity among offspring.
