BA mixture of maternal and paternal chromosomes
Correct Answer
CSame number of chromosomes as present in parent cell

During pachytene sub-stage of meiosis -I, crossing over i.e. exchange of genetic material take place between homologous chromosomes, which results in recombinations. The two homologous chromosomes are contributed by different parents. One of them is paternal chromosome and the other one is maternal chromosome.
So, the correct answer is 'A mixture of maternal and paternal chromosomes'.
