1. Alleles and Inheritance

Key Concepts & Definitions

  • Allele : A version of a gene found at a particular position on a chromosome.

★ Must-know

  • An individual inherits two alleles for a gene, with one allele coming from each parent.

Further detail

  • Alleles help determine which eye-colour trait an individual obtains when the parents have different eye colours, such as blue and brown.

Memory Hook

Two parental alleles meeting at the same chromosome position

2. Homozygous and Heterozygous States

Key Concepts & Definitions

  • Homozygous : When the two alleles are the same.
  • Heterozygous : When the two alleles are different.

Essential Points

📌 Homozygous and heterozygous describe whether the two alleles for a trait are the same or different, respectively.

Memory Hook

Homozygous means same; heterozygous means different

3. Dominant and Recessive Traits

Key Concepts & Definitions

  • Dominant Trait : Needs only one copy of an allele to be visible in an individual's appearance.
  • Recessive Trait : A trait that is dominated by a dominant trait.
