Chap 12 Flashcards
Johann Gregor Mendel
Father of genetics
On 1865 his results were presented to the Natural History Society of Brunn and were piblished in
1866
Traits and in dominant and recessive patterns as discreet units
Genes
Mendel was not recognized for his accomplishment until
1900
The sum rule states that the probably of the occurrence of
One event
These gene variants which exist at the same relative location on homologous chromosomes are called
Alleles
Alleles
Meiosis
Homozygous
Carrier
Heterozygous
Genotype
Since fertilization is a random event each possible combination is equally likely from a cross of two heterozygous and will produce a
Genotype ration
1 homozygous dominant, 2heterozygotes, and 1 homozygous recessive
Phenotype ratio
3:1
ABO human blood group (I^A I^B)
3
I^A I^B i
The recessive allele will remain
Latent
This law has its physical basis in the first division of
Meiosis
