What is a genotype and how does it differ from a phenotype? |
Genotype is a combination of traits and Phenotypes is the physical feature resulting from genotype. |
|
|
What is the definition of heredity and how does it relate to genetics? |
Heredity is passing down traits from parents to offspring. Genetics is the study of the traits. Genetics helps us understand how traits are passed down from parent to their children. |
|
|
What is the difference between dominant and recessive alleles? |
A dominant allele is stronger and has a capital letter while recessive is more weaker and has a lower case letter. |
|
|
What is the Law of Segregation? |
Law of Segregation is how genes separate when new sex cells are formed. |
|
|
What is the meaning of the term "true-breeding"? |
Plants are homozygous and are the same. |
|
|
What is a monohybrid cross? |
Monohybrid is where scientists study one trait at a time. |
|
|
What is the Law of Independent Assortment and how does it relate to dihybrid crosses? |
Law of Independent Assortment is the idea that the way one pair of genes is inherited doesn't affect the way another pair of genes is inherited. It relates to dihybrid crosses because it allows scientists to study the inheritance of two traits at the same time. |
|
|
What is the definition of probability and how is it used in genetics? |
Probability is how likely is something going to happen. Probability is used to predict the chances of certain trait being passed down from parents to offspring. |
|
|
What is a trait and what chemical factors determine traits? |
Traits are features on an organism. Chemical factors determine traits are called genes. |
|
|
What is the significance of Gregor Mendel's work with pea plants in the study of genetics? |
He noticed some traits are dominant and some traits are recessive and was able to predict what traits would appear in offspring based on the traits of their parents. |
|
|
What is Law of Dominance |
Some traits are dominate over others. |
