The branch of Biology which is concerned with studying the inheritance of traits and the variations caused by them

The designation for the parent generation

The physical and psychological traits of an organism

Alternate form of a gene

Distinguishing or unique characteristics which make one organism different from other organisms

The first filial generation, offspring from the cross of the P generation

Genetic make-up of an organism; remains constant throughout an individual's life.

Describes an individual with two alleles at one locus that are identical (hint: BB, or bb)

The unique trait an individual has (for example, brown hair)

The second filial generation, offspring from the cross of the F1 generation

In a heterozygous pairing, the allele that is fully expressed in an organism's phenotype

Describes an individual with two different alleles at a locus

The transmission of traits

An organism heterozygous for a trait

Allele that is not expressed in an organism's phenotype in a heterozygous pairing

What law states that when individuals of contrasting traits are crossed, the offspring will express only the dominant trait

Who performed a number of experiments which involved pea plants

Having descended from ancestors of a distinct type, or breed. (Hint, Mendel did this to obtain P generation)

A specific sequence of DNA that governs the expression of a particular trait and can be passed to an offspring

What is Mendel's ratio
