What is Genetics?

• The study of oceanography and marine life
• The study of genes, heredity, and variation in living organisms.
• The study of ancient civilizations and their artifacts
• The study of weather patterns and climate change

What is a Trait?

• A type of clothing fabric
• A unit of measurement
• A type of dessert
• A specific characteristic that varies

  from one individual to another.

What is an Allele?

• RNA's sister from new york

Gregor Mendel is the father of what?

A Genotype is the genetic makeup of an organism;

The gene (or allele)

• True
• false

what is an Punnett Square?

• A diagram used to predict the possible genotypes of offspring in a genetic cross
• A type of crossword puzzle
• A cooking utensil
• A type of dance move

Whats the diffrence between Dominant and Recessive alleles?

• Dominant traits are expressed when at least one dominant allele is present, while recessive traits are only expressed when two recessive alleles are present.
• Dominant traits are only expressed when two recessive alleles are present, while recessive traits are expressed when at least one dominant allele is present.
• Dominant traits are only expressed when two dominant alleles are present, while recessive traits are expressed when at least one allele is present.
• Dominant traits are expressed when no alleles are present, while recessive traits are expressed when at least one allele is present.

Draw a Punnett Square.

what is Incomplete Dominance?

• A genetic concept where the dominant allele is only expressed in certain environmental conditions, resulting in variable traits.
• A genetic concept where neither allele is completely dominant over the other, resulting in a blending of traits.
• A genetic concept where both alleles are recessive, resulting in the absence of the dominant trait.
• A genetic concept where one allele is completely dominant over the other, resulting in the suppression of the recessive trait.

what is Codominance

• One allele is completely dominant over the other
• Both alleles are partially expressed
• Both alleles in a heterozygous individual are fully expressed
• Codominance only occurs in homozygous individuals
