It is a powerpoint presentation that discusses about the lesson or topic: Mendelian Inheritance. It also talks about the definition, history and the laws included in the Mendelian Inheritance or Mendelian Genetics.

2. GREGOR MENDEL
• July 20, 1822 – January 6, 1884
• Born in Silesia, part of the Austrian Empire (now
known as the Czech Republic)
• Worked as a gardener and a beekeeper
• Joined the Augustinian Friars
• Experimented on Pea Plants
• Known as the “Father of Genetics”

6. LAW OF SEGREGATION OF GENES
• Every individual organism contains two alleles for
each trait, and these alleles segregate or become
separated during meiosis
• An offspring thus receives a pair of alleles for a trait
by inheriting homologous chromosomes from the
parent organisms: one allele for each trait from each
parent

7. LAW OF SEGREGATION OF GENES
• Homologous Chromosomes – it is a set of
paternal and maternal chromosomes that
are pair-up with each other inside a cell
during the stage of Meiosis

9. LAW OF INDEPENDENT ASSORTMENT
• The alleles, for separate traits, are passed
independently of one another from the parents to the
offspring
• 23 Chromosomes (Father) + 23 Chromosomes
(Mother)
• 46 Chromosomes in a normal human cell

10. LAW OF INDEPENDENT ASSORTMENT
• The chromosomes that result are randomly sorted
from all possible maternal and paternal
chromosomes.
• The zygote can end up with any combination of
paternal or maternal chromosomes.

11. LAW OF DOMINANCE
• It states that recessive alleles will always be masked
by dominant alleles
• A cross between a homozygous dominant and a
homozygous recessive will always express the
dominant phenotype, while still having a heterozygous
genotype
