Genetics Flashcards
Oogenesis results
Ovaries
Not continuous
Do not receive cytoplasm DNA
All cytoplasm is for primary oocyte
Oogonium
Diploid versus haploid
Diploid 2 n
Haploid is one set of chromosomes
What is the law of independent assortment ?
The law of independent assortment is two jeans on different chromosomes, segregate their alleles independently
What is the independent assortment product law?
The independent assortment product law is when two independent events occur simultaneously the combine probability of two outcome is equal to the product of their individual probabilities
How do you calculate chai square?
Estimate how frequently does deserve deviation can be expected to occur based on chance
( O-E)2/E
Incomplete partial dominates where is complete dominance
Incomplete partial dominance is where the heterozygous is a blend and intermediate
Call dominates is when different alleles that are both express in heterozygote
Two distinct and detectable genes are produced and exist.
What is epistasis?
Epistasis is the interaction of genes
The action of GENES is altered by another or several GENES
Epistasis is one gene affects the expression of a second gene.
What is pleiotropy?
production by a single gene of two or more apparently unrelated effects.
X-linked traits, male versus female
Mail, one excellent chromosome is hemizygous and inherited from mother and two possible genotypes
Female 2X chromosomes are inherited from both parents
Heterozygous are carriers of the recessive trait
X-linked dominant versus X-linked recessive traits
X-linked dominant inheritance Express in females with only one copy
Excellent recessive traits are always expressed in meals, meals inherited from their mother and expressive and females with one copy
Example color blindness
Recessive skipped a generation
Female homozygous show
Affective females get one from their affected fathers and affected mothers, who are heterozygous
What are sex influence traits?
Sex and food treats are traits in which the phenotype express by heterozygous is influenced by sEx
A Leo appears, dominant in one sex and recessive in the other
Example pattern baldness
What is incomplete penetrance be penetrance
Incomplete penetrates occurs when the disease of a phenotype is not always observed among individuals, carrying the disease associated with the genotype
Penetrance is percent of the individuals that show at least some degree of expression of a mutant genotype
What does variability express ability?
Variable expression, ability, denotes, the range of expression of median genotype
What is conditional mutations?
Conditional mutations are temperature sensitive
Enzyme activity functions at optional temperature
Lots of functional at higher temperatures 
What is the onset of disease?
Onset of disease is one age of onset disease, very at stage of development and growth, and have different genetic requirement
Increases severity of symptoms in successive generations
What is gnomic imprinting?
Do you know make a printing occurs when the expression of a gene difference when the allele is transmitted, maternally versus paternally
Parent of Irgun effect
What is extranuclear inheritance?
Extranuclear inheritance is the transmission of traits by DNA in mitochondria and chloroplast
What does heteroplasmy
 How do apply me is the condition in which mitochondrial DNA sequence is not the same in all copies
Phenotype may not be express
