a key part of business management and commerce that involves the process of creating, communicating, and delivering products or services to customers.
2. GREGOR MENDEL (1822-1884)
1. RESPONSIBLE FOR THE LAWS
GOVERNING INHERITANCE OF TRAIT.
2. STUDIED INHERITANCE OF TRAIT IN
PEA PLANT.
3. AUSTRIAN MONK.
3. PARTICULATE INHERITANCE
1. MENDEL STATE THAT PHYSICAL TRAITS ARE INHERITED AS
PARTICLES.
2. HE DID NOT KNOW THAT ACTUALLY THOSE PARTICLES ARE
CHROMOSOMES AND DNA
TYPES OF GENETIC CROSS
MONOHYBRID CROSS CROSS INVOLVING SINGLE
TRAIT EG.FLOWER COLOUR.
DIHYBRID CROSS CROSS INVOLVING TWO TRAIT EG.
FLOWER COLOUR AND PLANT HEIGHT.
4. GENETIC TERMINOLOGY
TRAIT ANY CHARACTERISTICS THAT PASSES FROM PARENTS TO
OFFSPRING.
HEREDITY ANY TRAIT THAT PASSES FROM PARENTS TO OFFSPRING.
GENETICS STUDY OF HEREDITY.
GENOTYPES GENE COMBINATION FOR A TRAIT (EG. RR, RR,
RR)
PHENOTYPES PHYSICAL FEATURES RESULTING FOR
GENOTYPE ( RED, WHITE ).
5. DESIGNER GENE
ALLELE TWO FORMS OF GENE
DOMINANT GENE WHICH EXPRESS IN F1 GENERATION
RECESSIVE GENE WHICH NOT EXPRESS IN FI
GENERATION
GENOTYPES
HOMOZYGOUS GENOTYPES GENE COMBINATION INVOLVING
2 DOMINANT AND 2 RECESSIVE GENE
HETEROZYGOUS GENOTYPES GENE COMBINATION
INVOLVING 1 DOMINANT AND 1 RECESSIVE GENE.
6. WHY PEA
GROW IN SMALL AREA
PRODUCE LARGE NO.OF OFFSPRING
PRODUCE PURE PLANT WHEN ALLOWED TO SELF POLLINATION SEVERAL
GENERATION
CAN BE ARTIFICIALLY CROSS
1. SNIP THE STAMEN TO PREVENT SELF POLLINATION
2. COVER WITH CLOTH BAG
3. HE TRACE THE TRAIT THROUGH THE SEVERAL GENERATION
9. MENDELS LAW
LAW OF DOMINANCE GENE WHICH EXPRESSIS DOMINANT OTHER ONE IS
RECESSIVE
LAW OF SEGREGATION GENES NOT MIX WITH EACH OTHER THEY ARE
SAPERATE FROM EACH OTHER
LAW OF INDEPENDENT ASSORTMENT ALLELES FOR DIFFERENT TRAITS ARE
DISTRIBUTED TO SEX CELLS INDEPENDENTLY OF ONE ANOTHER.
