All of the following options contribute to increasing genetic variation in sexually reproducing organisms:
a. **Crossing over** - This occurs during meiosis when homologous chromosomes exchange genetic material, leading to new combinations of genes.
b. **Independent assortment** - During meiosis, the way chromosome pairs orient themselves and separate is random, resulting in a variety of genetic combinations in the gametes produced.
c. **Mutation** - Mutations introduce new genetic variations into a population by altering the DNA sequence, which can create new alleles.
d. **Segregation** - This refers to the separation of alleles during gamete formation, ensuring that each gamete carries only one allele for each gene, contributing to genetic diversity.
Therefore, all options (a, b, c, and d) are correct as they all play a role in increasing genetic variation.
