What is the term for how traits are passed down to offspring?

Inheritance or heredity

300

What is something that is passed down from parents to offspring?

Traits or Genes

300

What are two reasons scientists rely on punnett squares

To predict the probability of a trait, and comprehend how genetics are inherited.

300

What is the difference between phenotype and genotype?

Phenotype is physical appearance, while genotype is the genetics.

300

What were the three generations of Gregor Mendel's experiments?

P generation, F1 generation, and F2 generation.

300

What are the different versions of a gene called?

Alleles

400

What is the probability of a homozygous recessive showing up between a cross of two heterozygous parents?

25%

400

What are one of two reasons scientists rely on Punnett Squares?

To predict the probability of a trait, or to understand how genetics work.

400

What is the trait when both alleles are present in the offspring and don’t mask each other?

Codominant trait

400

What was the ratio of dominant to recessive alleles for the F2 generation?

3:1

400

What is the term for the genetic makeup of an organism?

Genotype

500

In a cross between a homozygous dominant and a heterozygous, what are all of the possible genotypes?

AA and Aa

500

What is the probability of a homozygous recessive showing up in a set of a homozygous recessive and a heterozygous?

50%

500

What is the general name for the genotype in which two identical alleles are present and can be a dominant or recessive phenotype?

Homozygous

500

What was the law in which alleles separate during fertilization so gamete only gets one allele?

Law of Segregation
