Genes

This week in science we learned about dominant and reccesive genes. The dominant gene is always the visable one. This is also known as the phenotype. We also learned about the terms heterozygous and homozygous. Heterozygous is when the genes are different. One is the reccesive allele and one is the dominant allele (Rr) Homozygous is when the genes are the same (RR,rr) We did a lab on whether people could taste a chemical on a piece of paper or not. I missed the lab so i am not exactly sure what the results mean. I would guess it has to do with the strength of the tastebuds you inharrit from your parents. The hw where we traced a gene was interesting because it showed the possible genes i could have recived.
