• When applying molecular genetics techniques

Key Concepts

Mendelian Inheritance

Laws

1. Law of Dominance: Dominant masks recessive
2. Law of Segregation: Alleles separate
3. Law of Independent Assortment: Genes assort independently

Genetic Crosses

# Example: Punnett square analysis
def punnett_square(parent1, parent2):
    """
    Generate Punnett square for two alleles.
    parent1, parent2: 'A' or 'a' for each parent
    """
    gametes1 = [parent1[0], parent1[1]]
    gametes2 = [parent2[0], parent2[1]]
    
    offspring = [[g1 + g2 for g2 in gametes2] for g1 in gametes1]
    return offspring

def mendelian_ratios(genotypes):
    """Calculate expected phenotypic ratios."""
    AA = genotypes.count('AA')
    Aa = genotypes.count('Aa')
    aa = genotypes.count('aa')
    return {'dominant': AA + Aa, 'recessive': aa}

Non-Mendelian Inheritance

• Pleiotropy
• Epistasis
• Genomic imprinting
• Mitochondrial inheritance

Molecular Genetics

• DNA replication
