front 1 Linkage | back 1 Association between genes that are on the same chromosome. |
front 2 coupling configuration | back 2 Arrangement of linked genes in a dihybrid cross where the two dominant genes are on one chromosome and the two recessive are on the other chromosome |
front 3 repulsion configuration | back 3 Arrangement of linked genes where the linked genes in a dihybrid are one dominant and one recessive on one chromosomes, same vice versa. |
front 4 cis dihybrid | back 4 Dihybrid where the alleles are in coupled |
front 5 trans dihybrid | back 5 dihybrid where the alleles are in repulsion |
front 6 tetrad | back 6 The four haploid products of a single meiosis. |
front 7 octad | back 7 ascus with eight ascospores where produced from a tetrad that under went another mitosis. |
front 8 first division segregation | back 8 different alleles go into different nuclei in the first meiotic division, produces M1 segregation in ascus |
front 9 second division segregation | back 9 different alleles go into different nuclei in the second nuclei division, produces M2 segregation in ascus |
front 10 molecular marker | back 10 a site where there is difference in DNA that isn't necessarily associated with difference in phenotype that's used as a tag for a particular chromosome locus |
front 11 restriction enzyme | back 11 An enzyme that will recognize a particular sequences of DNA and target in and cut the DNA at those points. |
front 12 simple sequence length polymorphism (SSLP) | back 12 The presence of short respective DNA sequences, in different amounts at a particular locus on homologous chromosomes |
front 13 haplotype | back 13 genetic class describe by DNA sequence that are together on a physical chromosome. |
front 14 complete dominance | back 14 alleles which when combined in heterozygous will display a phenotype undistinguishable from one of the homozygous |
front 15 haplo-sufficiency | back 15 One copy of the normal/ wild type gene is enough to confer to the normal phenotype |
front 16 haplo-insufficiency | back 16 One copy of the normal gene is not enough to give the normal phenotype. |
front 17 codominance | back 17 alleles when combined in heterozygous display phenotypic traits from both homozygotes |
front 18 incomplete dominance | back 18 Alleles when combined in heterozygous will display a phenotype between the two homozygotes |
front 19 lethal allele | back 19 A allele that expression will result in death to the individual, could be recessive or dominant. |
front 20 pleiotropic mutation | back 20 a mutation that affects several phenotype traits |
front 21 prototroph | back 21 wild type strain that can survive on min medium |
front 22 auxotroph | back 22 won't survive on min medium |
front 23 complementation test | back 23 test for determing if mutations are on the same gene or not. diff genes they compliment |
front 24 Selective medium | back 24 Only certain genotypes are able to |
front 25 Differential medium | back 25 Genotypes can be distinguished from |
