recombinant
Figure 7.3 In this illustration of the effects of crossing over, the blue chromosome came from the individuals father and the red chromosome came from the individuals mother. Crossover occurs between non-sister chromatids of homologous chromosomes. The result is an exchange of genetic material between homologous chromosomes. The chromosomes that have a mixture of maternal and paternal sequence are called recombinant and the chromosomes that are completely paternal or maternal are called non-recombinant.
