Delivery of characteristics from parent to offspring.

Sequence of DNA that determines a trait.

Gregor Mendel used these plants for his genetic studies.

The characteristic of an organism, what it looks like, color, texture, height etc.

Different form of a gene. Round or wrinkled or yellow or green. Like vanilla and chocolate ice cream different flavors but still ice cream.

Genes are inherited in _______ of alleles.

Trait that masks or hides the recessive trait. Always represented by a capital letter.

Always represented by a lower case letter. Doesn't show if a dominant allele is present. Need 2 of them for the trait to show.

Genetic make-up of an organism. What the paired alleles look like.

Physical characteristics of the organism.

Paired alleles are the same. Like AA or aa.

Paired alleles are different. Like Aa or Bb. One dominant and one recessive.

Organisms that have a heterozygous genotype are known as. Like Rr.

Organisms that have homozygous alleles are considered? Like AA or aa

Mendels Principle that states that if a dominant allele is present in the genotype then the dominant trait will show.

____________ dominance means the the dominant alleles completely masks recessive alleles. There is no in between.

Which genotype is homozygous dominant?

Which genotype is heterozygous?

Which genotype is homozygous recessive?

What would be the phenotype of a mouse with a genotype of bbEe ?

Mendels principle that states, the alleles of two different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene.
