syndrome with isochromosome of 12p
what is the inheritance pattern of VNTRs
codominance
alleles of linked genes usually segregate together during meiosis. when they don’t, it is because _________ has occurred between them
crossing over
if too little time has passed for crossing over to random haplotypes or if natural selection favors certain haplotypes, what would you expect to see
linkage disequilibrium
specific array of alleles making up set of linked genes on single chromosome is called a
haplotype
what genes is responsible for aniridia (WAGR)
PAX6
where would you expect to see highly repetitive regions of DNA known as satellites
short arm of acrocentric chromosome
studies of infants born w/ DS have established over 90% of causes can be attributed to what chromosomal abnormality
maternal meiosis I nondisjunction of chromosome 21

suppress
does polyploidy increase fertility?
no
ex. of heterochromatin
