| Question | Answer |
|---|---|
| How can you find the ratio of genotypes in a generation? | by counting the number of the squares with each genetic combination |
| How many alleles does each parent have for each gene? | Two |
| How many alleles does each parent contribute to the offspring? | One |
| What does homozygous mean? | The same |
| What does heterozygous mean? | Different |
| The Homozygous parent will give the offspring a _____ allele. | Recessive |
| The organism with the recessive phenotype must be ____. | Homozygous recessive |
| What is a dihybrid cross? | a cross that examines the inheritance of two different traits |
| What did mendel begin his crosses with? | Purebred plants |
| What is the law of independent assortment? | it states that allele pairs separate independently of each other during gamete formation |
| The result of Mendels dihybrid crosses can also be illustrated with? | A punnett Square |
| What is Probability? | The likelihood that a particular event will happen |
| What is the probability of a coin landing on heads? | one out of two |
| Depending on how one coin lands, will it affect how the other coin lands? | No |
| What is the probability that a gamete will get a dominant allele? | one out of two |
| What is the probability that a gamete will get a recessive allele? | one out of two |
| what is a monohybrid cross? | A cross that examines only of specific trait |
| What is a Punnett square? | a grid system for predicting all possible genotypes resulting from a cross |
