Topics in Heredity

1

Accumulation of Variation During Reproduction

  • Reproduction creates individuals that are similar but subtly different from their parents
  • Each generation inherits differences from previous generation plus newly created differences
  • Asexual reproduction creates minor variations due to small DNA copying errors
2

Inherited Traits and Mendel's Laws

  • Gregor Mendel studied inheritance patterns in pea plants (1822-1884)
  • Both parents contribute equally to offspring's genetic material
  • Each trait has two versions (alleles) in each individual
3

Mechanism of Trait Expression

  • Genes are sections of DNA that code for specific proteins
  • Proteins (especially enzymes) control the expression of traits
  • Example: Plant height depends on hormone production controlled by enzymes
4

Sex Determination

  • Sex determination varies across species - environmental or genetic
  • Some reptiles: temperature determines sex during egg development
  • Some animals like snails can change sex
