The Science of Genes. Ro Hillenbrand

Genetics. DNA. Deoxyribonucleic acid. The things that make us, us.

Eye Color Chart

Eyes, hair, likes, dislikes, tastes, allergies. They all come along with genes.

Alleles. One set from your mother, and one from your father. The alleles code the genetics to give you your appearance. You then have a nucleus with 23 chromosomes in it.

Dangling Earlobes and Attached Earlobes

Dominant and Recessive.

The example above, the attached and dangling earlobes, is dominant and recessive traits in action.

Punnet Square

The punnet square is what allows us to see what is most likely in terms of what you're child will look like. Example, eyes.

There's an estimated 55% of brown eyes, 8% blue eyes, 2% green, and 5-8% hazel.

What Mutated DNA May Look Like

Mutations can happen within the DNA, changing the way one looks or acts.

Hypertrichosis is often referred to as werewolf syndrome. It's the excessive amount of hair growth on the human body.

This is what Hypertrichosis looks like

Sirenomelia, also called mermaid syndrome, is a rare disorder that fuses the legs together, giving the appearance of a mermaid tail. People with this disorder don't live long, and it's a miracle for the kids who live as long as they do with this disorder.

These disorders are from genetics. Some may not, and they could be from expulsion, or from an incident that could result in brain damage.

There's also down syndrome. It happens when there's a copy of chromosome 21, the nucleus of each cell contains 23 chromosomes.

The added genetic material alters the course of development, causing the characteristics of Down Syndrome.

1 in every 700 babies are born with down syndrome in the US, making it the most common chromosomal condition. 6,000 babies in the US are born with Down Syndrome each year.

Thank you for listening, and I encourage you to go and discover more, it's pretty interesting with what you can find in even just an hour.

A Few Definitions

These definitions are found off of Google, and you may take a look at them quick right here if you are slightly confused.

Chromosome- a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

Alleles- one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

DNA- deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.

Some Sources

The video I'm recommending are for the basics, the video is a two parter that gave me the interest in genetics, because it was tied with video games, and proving from the genetics a video game character's parents. It was what got me interested, and if reading doesn't interest you and you want a better explanation, here's the first part.

Game Theory Genetics-

Once again, thank you for listening, and have a great day.
