Mendel created the parental generation by allowing the two varieties to ____ pollinate separately.

The differing forms of a single trait are called _________.

Individuals with even one allele for sickle-cell anemia are immune to ____________.

The passing of traits from parents to offspring is called ___________.

Eye color is determined by the genes we inherit from our parents.

Incomplete dominance is VERY similar to the rejected __________ Theory of Inheritance.

What genotype would be in the bottom right box?

Each gene is a sequence of ____________ on an organism's DNA.

Females with one allele for a sex-linked trait and one unaffected allele are called __________.

This is called the Law of ______________.

What is an example of a sex-linked trait in humans?

Each allele is a slightly different sequence of nucleotides that produces a slightly different _________.

The genetic make-up of an individual is called the ___________.

Heterozygous individuals have two _________ alleles.

Mendel then cross-pollinated the two varieties, producing the first filial, or _____ generation.

What VERY IMPORTANT types of cells in humans are controlled by codominant genes?

The pea plant can self-pollinate and be cross-pollinated, allowing Mendel to control mating.

Which of the following is NOT a way mutations can occur?

Which of the following types of inheritance go against Mendel's laws?

________________ is when an individual is observed to have an "intermediate" or "blended" phenotype.

In Mendel's model of Complete Dominance, dominant alleles will ___________ recessive alleles.

Sex-linked traits coded for on the X chromosome occur more often in _________.

Who was the scientist that determined that some genes followed incomplete dominance inheritance?

What would be the genotypic ratio of this Punnett Square?

Mendel's experiments involved the same plant as Knight's experiment. What was it??

Mendel also concluded that an individual inherits one of these factors from each ________.

Which of the following human traits are controlled by multiple genes?

Which of the following is NOT one of the traits of pea plants that Mendel studied?

What genotype would be in all the boxes?

Mutations in humans which cause harmful symptoms are called genetic ________.

____________ are the source of new alleles.

Hemophilia is a _____________ genetic disorder

Mendel then allowed the F1 generation to self-pollinate, producing the second filial, or ____ generation.

Homozygous individuals have two ___________ alleles

The F1 generation had all purple flowers.

What would be the phenotypic ratio of this Punnett Square?

Which of the other traits in pea plants had a 3:1 ratio?

The belief that a person's traits are a combination of their parents' traits is called the ______ Theory of Inheritance.

____________ occur(s) when neither allele is dominant over the other, and both are seen in different parts of the body.

Mendel also concluded that a trait may not appear in an individual but can still be passed on to __________.

In polygenic traits, the number of different phenotypes will _________ if more genes control that trait.

Which of the following is NOT a human genetic disorder?

This is called the Law of _____________ Assortment

Mendel proposed a set of ________ that accurately predict patterns of inheritance.

Mendel concluded that the inheritance of specific traits is determined by _________.

This cross led to 705 purple-flowered plants and 224 white-flowered plants.

Tattoos are a genetic trait that we inherit from our parents.

This ratio of purple to white flowers can be reduced and approximated to a _____ ratio.

Gregor Johann Mendel also studied the experiments of a British farmer named ____________.

The garden pea is small, easy to grow, quick to mature, and produces many offspring.

The observed trait, or physical appearance of an individual is called the ____________.

Which of the following genotypes will appear with the intermediate phenotype?

_______________ are controlled by genes stored on either the X or Y chromosome.

Traits are controlled by two factors, one dominating the other, which separate when _________ are produced.
