Genetics Chapter 4.2

Genetics Textbook Chapter 4.2 Key Terms and Concepts

TermDefinition
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.
