Basic Genetics Hw =)

After going to the website I learned a couple of things. One thing I learned was about traits is that there are three types. Physical traits (phenotype), behavioral traits, and predisposition to a medical condition. What I learned is that all of these traits can be influenced by an environment even physical traits. Physical traits such as hair color can be easily changed by exposure to sun or hair dyes. Behavioral traits can be influenced by your surroundings also. People can have a huge effect on someones behavior. Risk of getting a medical condition can be effected by out environment too. For example exercising and eating healthy will lower the risk of heart disease. Another thing I learned about traits is how they are inherited. Each of the parents pass one of their alleles to their children. The two combined decides what trait they have. The combination is different every time they have a baby too.

What I learned from heredity is that parents randomly pass chromosomes to their babies. They provide one full set of chromosomes to their babies. The thing is that any of these chromosomes can be from any of the two sets of chromosomes that the parents have. Another thing is that the baby can only have one of each chromosome. Every child inherits unique chromosomes. Since all the children have different chromosomes from their parents some will look like the father and and some will look like the mother. When these babies grow up and start families of their own and have children they pass some of their own chromosomes to their children. This continues generation after generation.


This has been a great review and it has also taught me some new things.
