Mendelian genetics

• Homozygous has two same copies of the same allele (RR or rr) coding for a particular trait.
• Heterozygous contains two different copies of alleles (Rr) coding for a particular trait.
• Dominant Traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exist.
• Recessive Traits trait which are hidden or which does not appear.
