Answer:
If the paired chromosomes fail to separate during meiosis in the female, then the resulting daughter cells will receive either 2 or no copies of chromosome 21. If the resulting egg with 2 copies of chromosome 21 is fertilized with a normal sperm, the resulting zygote with be trisomy 21
Explanation:
Evolution is the change in heritable traits of biological populations over successive generations.
What is evolution of life?
- Evolution has produced the variety of life that exists on Earth today. Since life first emerged on Earth between 3.5 and 4 billion years ago, it has continued to develop.
- At initially, there were just single-celled, primitive species on Earth.
- The first multicellular organisms appeared much later, and as a result, the diversity of life on Earth significantly increased.
- Darwin put out a substantial amount of evidence to back up his idea of evolution by natural selection.
- Evolution is the gradual alteration of a living thing's traits over time. Natural selection is the process of evolution.
- Through their DNA, organisms transmit their traits from one generation to the next.

In a dehydration synthesis reaction, water is always formed as a by-product of the reaction.
<h3>What is a dehydration synthesis reaction?</h3>
A dehydration reaction in chemistry is a chemical process in which the reacting molecule or ion loses water. The opposite of a hydration reaction, dehydration reactions are frequent processes.
Dehydration synthesis is a chemical reaction that joins two smaller molecules by eliminating atoms from each of them. Organic compounds can be further divided into aliphatic and aromatic compounds based on the structure of hydrocarbons. The generation of new compounds with changes in atom bonding can occur in a variety of chemical processes involving organic molecules.
