SCIENCE ( GENETICS & HEREDITY )

• Gregor Mendel

  •father of genetics

  •proned on the study of genetics
• Genetics

  It is the study of genetics/heredity
• Heredity

  1. Is the transfer of traits through genes
  2. From parents
  3. Offspring
  4. Responsible for traits such as : eye color,skin color
• Reginald Punnet

  -the creator of the Punnet Square
• Gene

  Is always in pair which determine the maternal and paternal trait
• allele -can be presented by a pair of letters called genotype
• Dominant

  • Palaging nanalo
  • Malakas
• Recessive

  -mahina
• Homozygous

  • Two same alleles
• Heterozygous

  -two different alleles
• Genotype

  • Genetic composition for a trait of an genotype (cannot be seen)
• Phenotype

  • Genetic appearance ( seen)
• Monohybrid Cross

  • Involves a cross using a single factor or character trait
• Dihhyrid Cross

  • Involves a cross using two character traits
• Punnet Square

  • A diagram that allows us to determine the possible combinations of genes in a give cross
• Law of Dominant

  • States that one member of the pair of factors or genes may masks or hide the appearance of the other genes
• Genotype

  • Genetic Appearance ( cannot be seen)
• Law of Segregation

  • States that during gamete formation,the all pairs of segregation for all traits of an organism separate from each other
• Law of Independent Assortment

  • States that the distribution of one pair of genes is independent of the distribution of the other pair
