WHAT IS PANGENESIS THE THEORY OF, AND WHO MADE IT?
- THE THEORY OF INHERITANCE
- ARISTOTLE
WHAT DOES PANGENESIS STATE?
THAT GAMETES CONSIST OF PARTICLES (PANGENES) THAT FORM ALL OVER THE BODY AND WHEN FERTILIZED, GO THE THE PLACES THEY WERE FORMED
ANTHONY VAN LEEUWENHOOK SAW SPERM IN SEMEN AND THINKS HE SAW…
A MINIATURE HUMAN
THE IDEA OF ______ WAS LINKED TO THE THEORY OF INHERITANCE
- BLENDING
WHO IS THE FATHER OF GENETICS?
GREGOR MENDEL
MENDEL FORMED THE FOUNDATION OF WHAT IDEA?
- THE MODERN THEORY OF INHERITANCE
WHAT PLANT DID MENDEL MAINLY STUDY ON?
PEA PLANTS
WHAT IS TRUE BREEDING PLANTS?
PLANTS THAT SHOW THE SAME TRAITS OVER GENERATIONS
WHAT IS A TRAIT?
A SPECIFIC CHARACTERISTIC OF AN ORGANISM
WHAT IS CROSSING?
THE FERTILIZATION OF A SECIFIC FEMALE GAMETE WITH A SPECIFIC MALE GAMETE
WHAT IS A PHENOTYPE?
THE PHYSICAL EXPRESSION OF A GENE
WHAT IS A GENOTYPE?
THE GENETIC FORMATION OF INDIVIDUALS WITH ALLELES
WHAT IS LOCUS?
THE LOCATION OF GENES ON CHROMOSOMES
DOMINANT ALLELES ARE EXPRESSED WHEN…
THEY ARE ALONE OR IN PAIRS; B
RECESSIVE ALLELES ARE EXPRESSED WHEN…
THE DOM. ALLELE IS ABSENT; b
WHAT ARE THE 3 TYPES OF HOMOZYGOUS AND STATE THEIR GENOTYPE CONFIGURATION(USE THE LETTER B)
HOMOZYGOUS RECESSIVE: bb
HOMOZYGOUS DOMINANT: BB
HETEROZYGOUS: Bb
WHAT ARE THE 2 WAYS THAT TRAITS ARE SHOWN?
- WHEN PUREPLANTS SELF-FERTILIZE PRODUCING PLANS WITH SAME TRAITS
- WHEN THRU CONTROLLED FERTILIZATION, CROSS-BREEDING IS DONE
WHAT IS THE P GENERATION?
THE PARENTAL GENERATION; USUALLY CROSSED
WHAT IS F1?
FIRST FILIAL GENERATION; OFFSPRING OF P GEN
WHAT IS F2?
SECOND FILIAL GEN; OFFSPRING OF F1 GEN
WHAT IS THE LAW OF SEGREGATION?
WHEN GAMATES FORM, 2 ALLELES OF A PAIR SEPARATE FROM EACHOTHER
EX: Aa TURNS TO A or a
WHAT IS THE LAW OF INDEPENDANT ASSORTMENT?
SEPARATION OF 2+ ALLELES THAT GIVES OTHER TRAITS THE CHANCE TO FORM
EX: AaBb turns to AB, Ab, Ba, ab
WHAT IS A MONOHYBRID CROSS?
WHEN ONLY 1 TRAIT IS MONITORED FOR
WHAT IS A DIHYBRID CROSS?
A CROSS OF 2 ORGANISMS DIFFERING IN 2 TRAITS DUE TO 2 DIFFERENT GAMETES
WHAT DOES THE F2 RATIO OF INHERITANCE MEAN?
9: THE DOM TRAITS OF BOTH
3: THE 1 DOM AND REC OF EACH TRAIT
3: THE OTHER DOM/RECESSIVE OF EACH TRAIT
1: THE REC. FORM OF BOTH TRAITS
