Fundamentals of Genetics

When two alleles are present, the stronger allele that is always expressed is _______.

When neither allele for a trait is completely dominant over the other and blending occurs 

This law states that alleles of different traits separate independently from one another.

What is the offspring's genotype in the box with the ?:

What would be the phenotype ratio for the following Dihybrid Cross:TtAa   x    TtAa

What do the "Letters" on the outside of a Punnett Square represent?

“Father of Genetics” whose studies formed the basis for Modern Day Genetics.

Diagram/Chart used to predict the outcome of a genetic cross is a(n)

Alternate alleles for a trait that are equally dominant to one another (both seen) is called

The genotype (PP) is an example of this type of trait.

In the following cross where T= tall plant and t= short plant, what is the phenotype ratio?

The Branch of Biology that deals with  heredity is called ____________.

Mendel's first offspring generation was called the _____ generation.

A gene is a segment of DNA on a chromosome that codes for a certain protein (trait).. (T or F)

Two different alleles for a trait is called ______.

Gametes carry several alleles for each individual trait.  (T or F)

Two of the same alleles for a trait is called ______.

A cross involving only one trait is called a _______.

Express as a ratio: 25% Homozygous Dominant; 50% Heterozygous; 25% Homozygous Recessive

What is the correct Genotype for an individual who is heterozygous for a given trait?

What do we call the likelihood that a chance event will occur?

What genotype is always used in a test cross?

What do the "Letters" inside each box of a Punnett Square represent? 

An individual's set of alleles/gene combination (ex-Dd) is referred to as the individual's___. 

What do we call an allele for a trait that is not always expressed (the weaker allele)? 

This law states that two alleles for a single trait separate when gametes are formed.

The passing of traits from parent to offspring is called _________.

One of the two alternate forms of a gene for a specific trait is called a(n) _______.

The type of cross performed when the dominant phenotype is expressed with an unknown genotype. 

Mendel's F₂ offspring were called his ______________ Generation.

What type of cross involves two separate traits?

The physical appearance of a trait is referred to as an individual's ____________.
