Mendel's Law of Dominance: • Genetics (Part-1): Heredity | Inheritance | Genes | Variation Explained 👇 • • Genetics (Part-1): Heredity | Inherit... • Genetics (Part-2): Alleles | Dominant Recessive | Homozygous Heterozygous Explained! 👇 • • Genetics (Part-2): Alleles | Dominant... • Definition: One allele (dominant) masks the effect of another allele (recessive) for a particular trait. • Key Points: • 1. Dominant Allele: Expressed in the phenotype, even when paired with a recessive allele. • 2. Recessive Allele: Not expressed in the phenotype, unless paired with another recessive allele. • 3. Genotype: The combination of alleles (e.g., TT, Tt, or tt). • 4. Phenotype: The physical characteristic expressed (e.g., tall or short). • Examples: • 1. Height: Tall (T) is dominant, short (t) is recessive. • TT or Tt: Tall phenotype • tt: Short phenotype • 2. Seed Color: Green (G) is dominant, yellow (g) is recessive. • GG or Gg: Green phenotype • gg: Yellow phenotype • Symbolism: • Capital letter (T, G): Dominant allele • Lowercase letter (t, g): Recessive allele • Importance: • 1. Predicts the expression of traits • 2. Explains the 3:1 ratio of dominant to recessive traits in the F2 generation • 3. Fundamental concept in genetics, influencing inheritance patterns • Interesting Fact: • Mendel's Law of Dominance applies to many traits, but some exhibit: • Incomplete dominance (blending of alleles) • Co-dominance (both alleles expressed equally) • Polygenic inheritance (multiple genes influencing a trait) • #MendelsLawOfDominance #Genetics #DominantRecessive #Biology #Inheritance #TraitInheritance #GeneExpression #MendelianGenetics #HereditaryTraits #GenotypeVsPhenotype #Alleles #DominantAllele #RecessiveAllele #GeneticInheritance #Biotechnology #ScienceEducation #Mendel #Dominance #Genetics #Biology #Inheritance #GeneExpression
