Basic Principles of Genetics How are traits controlled by dominant and recessive alleles? For example: Each person has two genes for eye color. When a person has two identical genes, they have that eye color. The gene for brown eyes is dominant (B),the gene for blue eyes is a recessive (b).If a person has one B gene and one b gene or two B genes, then that person will have brown eyes. If a person has bb eye genes, then the person will have blue eyes.
Co-dominance In co-dominance ,the alleles are neither dominant nor recessive . As a result, neither allele masked in the offspring .
Punnet Squares A tool that can help you understand how the laws of probability apply to genetics is called a Punnett square. A Punnett square is a chart that shows all the possible combinations of alleles that can result from a genetic cross. Geneticists use Punnett squares to show all the possible outcomes of a genetic cross and to determine the probability of a particular outcome.
The Human Genome Project The main goal of the Human Genome Project is to identify the DNA sequence of every gene in the human genome. When the Human Genome Project is completed, an encyclopedia of genetic information about humans will be available. Scientists will know the DNA sequence of every human gene, and thus the amino acid sequence of every protein.
