What Is Genetics??

For the genetics lab we had to go to two different sites to work on labs. One was the dragon genetics lab and the other one was the punnett square. The dragon genetics explained the relationship between phenotypes and genotypes, and then you create physical changes in the dragons. Then I went and worked on the punnett square that took a lot more time for me to finally understand what I was suppose to do. You had to make a cross between the two flies, homozygous with long wings and homozygous with vestigial winged flies. By doing these labs it allowed you to get more familiar with genetic inheritance and how you receive the genes that you do.What is genetic inheritance? Inheritance is the traits that you receive from each one of your parents. Everyone has two copies of every gene, one inherited from the mother and one inherited from the father which is known as alleles. So if we inherit our genes from our parents they why don’t we look identical to our parents. It is because we inherit half of our father’s chromosomes and half of our mothers. There are important parts that you should know in order to understand how to do a punnett square and doing the genetics lab. During the dragon genetics lab you got to see recessive and dominant genes. Recessive inheritance is both parents have a normal gene and a faulty, recessive gene. Parents are not affected by the faulty gene, but their offspring is affected. A dominant inheritance means a parent has a single faulty dominant gene. This overpowers the counterpart and has an affect on the parent. When the parent is affected and mates with a non affected and non carrier mate the offspring could or could not be affected. Genotypes and phenotypes are genes of an individual. Phenotypes are an individual’s physical or observable characteristics.
