Which one of the following statements regarding Genotypes and Phenotypes is false?

An organism with two different Alleles for a single trait is said to be Homozygous for that trait.

The expression of both Alleles for a trait in a Heterozygous individual illustrates __________ and an example of this would be the Genotype AB in the ABO Blood Groups.

Codominance

A Hybrid is an offspring from one variety of a type of organism.

False

The Environment can have no possible effect on the physical characteristics of an organism.

False

The "Father" of Modern Genetic Study worked with what type of organism in his famous studies?

Garden Pea plants

The Alleles an organism contains is known as its ________.

Genotype

If an Allele pair is the same and are represented by two uppercase letters (AA) in a pair of Alleles, the pair is considered to be ________ for its Genotype

Homozygous Dominant

The "Father" of Modern Genetics showed that only one of two Genes associated with a trait is present in Gametes due to the separation of Alleles during Gamete formation. This is known as the ___________.

Law of Segregation

Who discovered and wrote a Genetics Law about the Independent Assortment of Genetic Factors (or Homologous Chromosomes)?

Mendel

Who is consideredto be the "Father" of Modern Genetic study?

Mendel

Different versions of the same Gene are called Alleles. An example would be one Allele which codes for red flower color vs. another Allele which codes for blue flower color.

True

The genetic makeup of an organism constitutes its Genotype.

True

The physical expression of traits in an organism are called its' Phenotype (what its' Characteristics look like).

True

The region of a Chromosome where an Allele occurs is called its' Locus.

True

Research has established that the Law of Segregation of Genes during Gamete formation _________.

applies to all sexually reproducing organisms

How many Sex Chromosomes are in a Human Gamete?
