Answers

A1. Genomics

Because genomics is the field of study that deals with the complete set of an organism's genetic material, including the interactions of genes with each other and the environment.

A2. Down syndrome

Because Down syndrome is caused by the inheritance of an extra copy of chromosome 21.

A3. Gene expression

Because gene expression refers to the process of using the information stored in a gene to create a functional product, which in many cases is a protein.

A4. Punnett square

The Punnett square was developed by Reginald C. Punnett in 1905 to help geneticists visualize how alleles segregate and combine during inheritance.

A5. Polymerase chain reaction (PCR)

Because Polymerase chain reaction (PCR) is a technique used to amplify a specific DNA sequence, allowing scientists to produce multiple copies quickly and efficiently.

A6. Polymorphism

Because polymorphism refers to the existence of multiple forms of a gene within a population, including those that are associated with specific traits or diseases.

A7. 1953

The discovery was the culmination of decades of collaborative efforts, with James Watson and Francis Crick publishing their double helix model in the journal Nature on April 25, 1953, based on X-ray diffraction images taken by Rosalind Franklin.
