    The correct option is Number 1. AaBb x AaBb

    Explanation:

    Genes can be described as basic hereditary units. The genes are made up of DNA.

    A gene carries two alleles for a particular trait. These alleles are present at the same loci in the homologous chromosomes. If the two alleles are similar then they are termed as homozygous e. g AA, BB. If the alleles for a trait are different then they are termed as heterozygous e. g Aa and Bb.
