During prophase I, all four chromatids of the two homologues become closely associated as a result of pairing, forming a structure known as a tetrad or bivalent.
<h3>What is a tetrad?</h3>
A tetrad is a structure formed during the prophase I stage of meiosis I whereby two homologous chromosomes pair together.
Meiosis occurs in two stages of division namely;
- meiosis I
- meiosis II
In meiosis I, homologous chromosomes are separated but are first paired during the prophase stage to form the tetrad or bivalent structure.
Therefore, during prophase I, all four chromatids of the two homologues become closely associated as a result of pairing, forming a structure known as a tetrad or bivalent.

<u>Answer:</u>
<em>16 kinds of gametes can be expected from an individual with the genotype ppccttrr. </em>
<u>Explanation:</u>
<em>Gametes are the haploid mature germ cells which can be both male and female.</em> They have the ability to unite to opposite sex in the reproduction phase to form a zygote.
<em>The example of gamete is the sperm that is ready to fertilize the egg during reproduction. </em>so there will be 16 types of reproductive cell with single <em>set of unpaired chromosomes with the genotype ppccttrr.</em>
