Document Summary
Longer regions have more crossovers and thus higher recombinant frequencies. Trihybrid females are test crossed with triple recessive males: Test cross is usually done with tester male because. Use branch diagram parental: why doesn"t the v and cv rf add up to 19. 6%? (18. 5%?) Different gene orders give different double recombinants ct v cv. Phenotypic ratios in progeny reveal the type of cross. Single nucleotide polymorphism (single nucleotide polymorphism s) gc to at: eg. Where are they: they can affect a gene leading to a phenotype. Pku or albinism you can be either homozygous or heterozygous for a snp but snps do not have to be in a gene or affect a gene. An rflp linked to a mouse disease gene. Minisatellite and microsatellite markers: most genomes contain a great deal of repetitive dna called simple sequence length polymorphisms (sslps) they are also sometimes called variable number tandem repeats or vntrs.
