Verified step by step guidance1
Understand that a tetrad is a group of four chromatids formed during meiosis by the pairing of two homologous chromosomes.
Recall that the haploid chromosome number (n) represents the number of distinct chromosomes in a gamete.
During meiosis, each chromosome pairs with its homologous partner to form a tetrad.
Since the organism has a haploid chromosome number of n = 4, there are 4 distinct chromosomes.
Therefore, 4 tetrads will form during meiosis, as each of the 4 chromosomes pairs with its homologous chromosome.
