what is linkage
when genes alleles are inherited together more often than not, indicates genes are close to each other on chromosome
what is recombination
the process of offspring’s deriving a new allele combination not seen in either parent through crossing over of non sister chromatids during meiosis 1
what are syntenic genes
genes liked on the same chromosome
what is a two point test cross
dihybrid crossed to a double recessive, used to find alleles contributed by dihybrid parent
even linked genes show some recombination if a large enough sample of progeny is examined
true, some parts of chromosomes will break off and reconnect with other homolog
explain the physical process of how recombination takes place
