Recombinant chromosomes have a mix of paternal and maternal alleles due to the process of crossing over during meiosis.

Here are the steps:

1. Meiosis is a type of cell division that reduces the number of chromosomes in a parent cell by half to produce four reproductive cells, each with half the number of chromosomes of the parent cell.

2. During the first division of meiosis (meiosis I), homologous chromosomes (one from each parent) pair up in a process called synapsis.

3. While the chromosomes are paired up, they can exchange segments of DNA in a process called crossing over. This is when the mix of paternal and maternal alleles occurs.

4. The points where the DNA is exchanged are called chiasmata. The resulting chromosomes, which have a mix of paternal and maternal alleles, are called recombinant chromosomes.

5. In the second division of meiosis (meiosis II), the sister chromatids of each chromosome are separated, creating four haploid daughter cells. These cells can develop into sperm or eggs.

6. When fertilization occurs, the paternal and maternal alleles can combine in new ways, creating genetic diversity in the offspring. This is one of the main advantages of sexual reproduction.
