| 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.
