The discovery of DNA is attributed to the research of three scientists in 1951; Francis Crick‚ Maurice Wilkins‚ and James Dewey Watson. They were all later accredited with the Nobel Prize in physiology and medicine in 1962. Thanks to their discovery‚ science has been able to research and learn from DNA blueprints and use recombinant DNA technology to discover answers‚ vaccines and build immunity for many viruses. In recent years science has been using this new technology to genetically modify animals

If a male with no freckles mates with a female who is heterozygous for freckles‚ what is the probability of their child having freckles? 3 Cystic fibrosis is transmitted by recessive inheritance. When 2 carriers of the disease mate‚ what is the probability that they will have a child with the disease? 4 Colorblindness is a condition in humans transmitted by a sex-linked recessive gene.

Last year‚ Opal went to the doctor for a strange lump in her breast. Thankfully‚ it was not cancer‚ but the doctor delivered a grim piece of news. She had a mutation in the BRCA1 gene‚ which meant a high likelihood of a cancer diagnosis later in life. Opal had no idea how to process the information‚ so her doctor sent her to a genetic counselor. Not everyone has the same opinion on going to the doctor‚ and definitely not everyone reacts to a diagnosis in a similar manner; highlighting why M.D.
