The chromosomes in the illustration below are found in a male betta fish and carry the gene for determining a trait in the tail of the betta fish. In betta fish, single tails are domi- nant to double tails. During meiosis, when gametes are formed, the male fish can only pass on one allele for the tail trait to each gamete. In a male fish that happens to be heterozy- gous, a gamete can only inherit the dominant allele on chromosome 1 or the dominant al- lele on chromosome 2. centromere paired homologous chromosomes chiasma An illustration of paired homologous chromosomes. homologous chromosome 1 homologous chromosome 2
