Gene Lab # 2

In this lab I learned how to take two parents and determine what they would look like. What genes they inherited from their parents. In the flies lab all of the offspring except for one looked exactly like their parents. The one received short wings instead of long. In the dragon lab my assignment was to make the offspring look like its parent. To be honest, I had trouble at first because I didn't finish reading the material. After reading the material it was pretty clear. Our gene inheritance is important not just for what we look like on the outside but what generations of genes have given us to adapt to what we do now.

In this punnett square both parents were heterozyous long-winged flies. 3 of the offspring also turned out to have long wings. 1 offspring did however get short wings.

Here in the dragon gene lab, it was fun changing alleles (genotype) to see what physical appearance would be (phenotype). By changing alleles, was able to make the offspring look just like the parent in the picture.

A genotype is genes of an individual for a particular trait or traits, often designated by letters, for example, BB or Aa. An example would be in both labs, changing the dragons alleles or picking the right fly parents. A phenotype is a visible expression of a genotype, for example, brown eyes or attached earlobes. Given the dragon horns or no legs, changing its color. A allele is an alternative form of a gene: alleles occur at the same locus on homologous chromosomes. The offspring with short wings. A cross is for example the fly. Both parents were heterozygous long winged flies the offspring will be 75% chance of being like their parents. A dominant allele is an allele that exerts its phenotypic effect in the hererozygote; it masks the expression of the recessive allele. For instance, the dominant allele in the flies were long winged. A recessive allele is an allele that exerts its phenotypic effect only in the homozygote; its expression is masked by a dominant allele. Again the long winged flies.

In conclusion, it is important to know how are genes are put together. It is always interesting to see what the dominant genes are even in our own families. Its awesome to see those recessive genes pop up when nobody knew they existed in the family.

With gene inheritance in other organisms, like plant or animals, the things that help them survive, or help us to survive even, is passed down in our genes for generations that don't know things. Our genes help us to adapt and other living organisms to also adapt over the years. We have become better survivalists by certain things passed down in our genes.
