Genetics Vocab #1: Mendelian

Characteristic that is inherited; can be either dominant or recessive.

• Trait

• The Law of Segregation

• Allele

• Homozygous

The alleles must separate when gametes are formed

• Trait

• The Law of Segregation

• Allele

• Homozygous

The different forms of a gene.

• Trait

• The Law of Segregation

• Allele

• Homozygous

Having two identical alleles for a given gene; homozygous dominant (RR), homozygous recessive (rr)

• Trait

• The Law of Segregation

• Allele

• Homozygous

Having two different alleles for a given gene.

• Heterozygous

• The Law of Independent Assortment

• Molecular genetics

• Cross

In dihybrid crosses, the alleles for the two traits segregate independently of each other when gametes are formed. So when looking at a parent with two traits there are four possible combinations when gametes are formed.

• Heterozygous

• The Law of Independent Assortment

• Molecular genetics

• Cross

the subfield of biology that studies the molecular structure and function of genes

• Heterozygous

• The Law of Independent Assortment

• Molecular genetics

• Cross

The mating of 2 organisms.

• Heterozygous

• The Law of Independent Assortment

• Molecular genetics

• Cross

the transmission of traits from one generation to the next

• Gregor Mendel

• Dominant

• F1 generation

• Heredity

the first generation of offspring obtained from an experimental cross of two organisms the P generation

• Gregor Mendel

• Dominant

• F1 generation

• Heredity
