Genetics Flashcards
Process of passing of traits
Heredity
One or two alternative form of a gene
Allele
Expressed gene
ex: B - black
Dominant
Suppressed gene
ex: b - blonde
Recessive
Combination of gene type
Homozygous
Combination of different gene type
Heterozygous
Gene combination
ex: BB, Bb, bb
Genotype
Gene expression
ex: Black, Brown, Blonde
Phenotype
Blending of traits
Law of Incomplete Dominance
Co-expression of two genes
Law of Codominance
All results have the same answer
Law of Complete Dominance
Type A and Type B are the only blood types to have heterozygous genotype
True
They are IAi and IBi
Inheritance of traits associated with the sex chromosomes
Sex Related patterns of inheritance
Autosomal traits that are influenced by sex
Sex-influenced traits
Controlled by autosomal genes limited to only one sex due to anatomical difference
Sex Limited traits
Dependent inheritance of trait due to a gene located in a sex chromosome
Sex-linked Traits
The female chromosome is X X
True
The male chromosome is Y X
False ; it is X Y
Recessive genetic disease which the person has inability to distinguish some colors
Color blindness
Recessive Disease characterised by progressive muscle degeneration
Duchene Muscular Dystrophy
Dmd
Milder form of DMD
causes slowly progressive muscle weakness
Becker Muscular Dystrophy
Recessive disease which the blood does not clot normally
Haemophilia
X-linked disorders
1) Color blindness
2) DMD
3) BMD
4) Hemophilia
Condition expressed as long hairs growing from the helix of the pinna
Auricular Hypertrichosis
Genetically inherited disease of the eye
Vision impairment
Retinitis Pigmentosa
Blood is controlled of 3 alleles
Multiple Alleles
Father of Modern Genetics
Was an Augustinian Monk
Gregor Mendel
