Storyboard Text

  • What are genetics?!?!
  • Ok class, today  we will learn about genetics!
  • Codominant traits also have two capital letters. These traits are formed when two homozygous dominant traits are crossed. For instance, if a flower that was dominant for being purple crossed with a dominant red flower, you would get a speckled purple and red flower! Can anyone guess what the genotype would be?
  • Tell us more!
  • Genetics is the study of heredity, or traits being passed from parent to offspring.
  • How interesting!
  • Genotypes are the genetic "code" for these traits while the phenotypes are the actual physical traits. An example of a genotype is Bb, which is heterozygous. An example of a phenotype is brown eyes, which are dominant to green eyes in this case.People can be homozygous dominant, heterozygous, or homozygous recessive for traits.
  • Correct! She did that by using a punnet square! I hope you learned something today!
  • Dominant traits mask recessive traits. For example, if a heterozygous male and a homozygous  dominant female both had brown eyes and had a baby, the chance of  them having a kid with brown eyes is 100 percent.
  • Homozygous dominant always has two capital letters, such as BB. Heterozygous has one capital and one lowercase letter, such as Bb. Homozygous recessive always has two lowercase letters, such as bb.
