Meiosis provides a chance for new combinations of chromosomes mainly by the phenomenon of crossing over and random distribution of homologous chromosomes between daughter cells.

Explanation:

Meiosis is a type of cell division that occurs in sexually reproducing organisms. It involves two successive divisions of a diploid cell, resulting in the formation of four haploid daughter cells. Meiosis is evolutionary significant because it leads to genetic diversity through recombination and provides the basis for sexual reproduction.

Genetically similar daughters:
- Option (a) states that meiosis results in genetically similar daughters. However, this is incorrect as meiosis actually leads to genetic diversity.

Four daughter cells:
- Option (b) states that meiosis results in four daughter cells. This is correct. During meiosis, a diploid cell undergoes two divisions, resulting in the formation of four haploid daughter cells. These daughter cells have half the number of chromosomes as the original cell.

Eggs and sperms:
- Option (c) states that meiosis results in the formation of eggs and sperms. While it is true that meiosis is responsible for the formation of gametes (eggs and sperms), this option does not encompass the full significance of meiosis.

Recombinations:
- Option (d) states that meiosis results in recombinations. This is the correct answer. Meiosis involves a process called crossing over, where genetic material is exchanged between homologous chromosomes. This leads to the rearrangement and recombination of genetic information, resulting in new combinations of genes. These new combinations contribute to genetic diversity within a population and are important for evolutionary processes such as natural selection.

Conclusion:
In summary, meiosis is evolutionary significant because it leads to the formation of four daughter cells, including eggs and sperms, and most importantly, it allows for genetic recombination. This genetic recombination through crossing over during meiosis results in the creation of new combinations of genes, leading to genetic diversity and providing the basis for adaptation and evolution.
