MODES OF INHERITANCE (PPT) Flashcards
It is transmitted on unbroken descent
Autosomal Dominant
Autosomal dominant is ________ and _______________ recessive.
Heterozygote; Homozygous
Autosomal dominant is ___________ mutant gene.
50%
It is between two heterozygotes and can be transmitted by a long line of carriers.
Autosomal recessive
It has 1/4 chance of being passed on and it is common in-breeding.
Autosomal Recessive
It has severe conditions that are unlikely to be passed on.
Autosomal recessive
The chance that both maternal and paternal alleles at one locus are identical by descent.
Coefficient of In-breeding
The proportion of all the individual’s genes are homozygous because of identity by common descent.
Coefficient of In-breeding
This is where two characteristics behave completely independently of each other.
Independent Assortment
What ‘cross’ do independent assortment use?
Dihybrid cross
The ratio that independent assortment produces which applies the principle of probability
9:3:3:1
This principle allows easy calculation of probability of genotypes and phenotypes among offsprings
Principle of probability
Under PRINCIPLE OF PROBABILITY
Impossible event : 0
Certain event: _____
1
If the probability of event x id p then the probability of “not x” is _________? `
1-p
The probability of two independent events occurring is the product of their two _________________
individual probabilities
When two independent events occur simultaneously, the combined probability of the two
outcomes is not equal to the product of their individual probabilities of occurrence.
Product Law
What are the mendel’s postulate?
Unit Factors in Pairs
Dominance and Recessiveness
Segregation
Studied varieties of peas (Stamen and Anthers) – self-fertilization and
cross-fertilization
Gregor Johann Mendel
Gregor Johann Mendel’s study among plants lasted from ___________; the result of his studies
was later published in ________.
1856-1868
1866
He is coined the “Father of Genetics”
Gregor Johann Mendel
The study of inheritance from generation to generation is known as _______?
Transmission genetics
