A tetrad is the pairing of homologous chromosomes. A human offspring inherits 23 chromosomes (N) from each parent upon fertilization, giving the offspring 46 chromosomes (2N). â¦ In meiosis, homologous chromosomes (N from mom and N from dad) come together and form a tetrad, which consists of 2 homologous chromosomes. Since you inherit a chromosome from both parents (2N) that pair up to form a tetrad, you will have 23 tetrads that have a chromosome from mom and dad paired together.
