Document Summary
Genotype genetic make up of an organism; specific set of alleles an organism carries. Phenotype the physical features of an organism; physical traits under genetic influence. Structural genes- the ones that carries the information to make proteins. Surrounded by regulatory regions contain regulatory genes. Regulatory genes initiate, promote, or terminate transcription. Think that regulatory genes are the most critical in determining the form of the organism. Chimpanzees and humans have 98% similar regulatory genes. All of these similarities come from regulatory genes. Abo refers to the protein that is found on the blood cell and refers to the gene on chromosome 9. We can be heterozygous (2 different alleles) or homozygous (2 same) The allele has to be expressed twice then its recessive. If the allele can be expressed once then its dominant. There are genes that are linked to this. Likely a combination of alleles that make someone more prone to be obese.
