1) Biological field or sub-topic chosen:
2) Define field or sub-topic:
Genes are always passed down from generation to generation. Things that are hereditary aren’t always going to be the case with everyone. The genes will not always be dominant.
3) Describe in more detail the breath and depth of what could be studied or learned within this topic:
4) Focusing on one major concept, principle, or group of organisms (as appropriate within the topic), describe its importance, relationships, functional aspects, or otherwise explain it in more depth as seems important to you and (potentially) the others in class:
The major concept that I am focusing on is Identical twins, I am an identical twin and I have always been curious of the genetics and wanting to know if the myth is true about skipping generations. There are two types of twins - identical and fraternal. To form identical twins, one fertilized egg (ovum) splits and develops two babies with exactly the same genetic information. This differs from fraternal twins, where two eggs (ova) are fertilized by two sperm and produce two genetically unique children, who are no more alike than individual siblings born at different times. Twins are slightly more likely to be female than male (50.3 per cent). Contrary to popular belief, the incidence of twins doesn't skip generations. The information I have found out about identical twins has proved my myth to be false because more the one source that I have researched said that it doesn’t necessarily skip generations.
5) In studying and discovering more about this topic, what was the most interesting aspect, fact or some other piece of information that you have learned.
6) References provide references used and at least two Web sites with additional information on this topic (or sub-topic) for anyone that would like to learn more:
