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;

  1. meiosis I
  2. 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.

The bottleneck effect is used to describe an event where a population decreases. One example involves the northern elephant seal
Svet_ta [14]
I think the best phrase to describe this would be Founder effects. Founder effects occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have; a non-random sample of genes in the original population. Reduced variation from the original population.. According to Bottlenecks and founder effects, genetic drift can cause big losses of genetic variation for small populations.

Based on the simulation, write a definition for the term "balanced chemical equation?
Elodia [21]
Since I have not seen the simulation, I can give a generic definition. A balanced chemical equation is when the mass of each element of the reactants (left side) is equal to the mass of each element in the products (right side). Make sure that all of the elements have the same amount on each side.
