mendel and his peas🫥 Flashcards
Describe Mendel’s experiments.
What did Mendel conclude about inherited traits?
Mendel concluded that two genetic factors control each inherited trait.
What are dominant and recessive traits?
A dominant trait is a genetic factor that blocks another genetic factor. A recessive trait is a genetic trait that is blocked by the presence of a dominant factor.
Understand how to use and read a punnent square.
What are genes and alleles?
A gene is a section on a chromosome that has genetic information for one trait. Alleles are different forms of a gene.
What is a pedigree?
A pedigree shows phenotypes of genetically related family members. it can also help determine geneotypes.
Understand how to read a pedigree.
What are the types of dominance?
Incomplete Dominance- when the offspring’s phenotype is a combination of the parent’s phenotype
Codominance- when both alleles can be observed in a phenotype
Polygenic inheritance- when multiple genes determine the phenotype of a trait
How does the environment affect an organism’s phenotype?
Environmental factors, like temperature, sunlight, and soil can affect phenotype.
Know the scientist’s who helped develop the knowledge of DNA’s structure.
What are the steps of making a protein?
What are mutations? Know the three types.
Mutations are changes in the nucleotide sequences of a gene. The three types are
