Chapter 10-11 Test Flashcards
What happens if an Autosomal Dominant Disorder has two dominant alleles
it is lethal
is Albinism recessive or dominant? What does it do
Recessive. defect of melanin that results in little pigment in skin and eyes
is Cystic Fibrosis recessive or dominant? What does it do?
Recessive. causes musuc buildup in lungs and/or digestive track. life-threating
is Achondroplasi recessive or dominant? What does it do?
dominant. causes dwarfism
is Galactosemia recessive or dominant? What does it do?
Recessive. body is unable to metabalize galactose
is Alzheimer’s Disease recessive or dominant? What does it do?
dominant. causes loss of brain functuin
is Huttington’s Disease recessive or dominant? What does it do?
dominant. causes brain to degenerate
what does monacious mean?
2 sexes in one organism
what does diacious mean?
sperate sexes
What is Mendel’s Law of Indepent Assortmant
states that allele pairs separate independently during the formation of gametes. This means that traits are transmitted to offspring independently of one another.
What is Mendel’s Law of Segregation
sates that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization.
What is Mendel’s Law of Dominance
states that one of the factors for a pair of inherited traits will be dominant and the other recessive, unless both factors are recessive.
Incomplete dominance
traits are blended (ex. red+white=pink)
c0-dominanat
both traits who up (Blood Type A+Blood Type B=BLood Type AB)
What happens in a higher crossover frequency
they are farther apart and have a higher chance of crossing
