Question

Meiosis results in a reassortment of maternal chromosomes (inherited from the mother) and paternal chromosomes (inherited from the father). if 2n = 6 for a given species, what is the probability that a gamete will receive 1 maternal chromosome and 2 paternal chromosomes?

Answer 1

The probability is 1/16 that a gamete will receive only paternal chromosomes. In life cycles that alternate between haploid and diploid stages, fertilization doubles the number of chromosomes per cell, The pairing of chromosomes along their lengths , which is essential for crossing over is referred to as synapsis
