Genetics Textbook Chapter 4.2 Key Terms and Concepts
Term | Definition |
---|---|
Probability | The method of predicting what trait offspring is most likely to inherit |
Punnet Square | A Punnet Square is used to see all the possible genotypes for offspring |
Phenotype | All of the physical characteristics an offspring could inherit |
Genotype | All of the characteristics an offspring could inherit in the form of the letters from the Punnet Square |
Homozygous | A purebred for a particular trait |
Hetrozygous | A hybrid for a particular trait |
Codominance | When the parent traits combine in the offspring |
What is probability and how does it help explain the results of genetic crosses? | Probability is the method of predicting what trait offspring is most likely to inherit and is used in Punnet Squares to determine the most likely trait for the offspring |
What is meant by genotype and phenotype? | Genotype are the characteristics still in letter form from the Punnet Square, but phenotype are the characteristics in trait form. (EX: Bb vs. Blue eyes) |
What is codominance? | Codomanince is when the both parent traits combine in the offspring and both are expressed. |
