the genes are physically connected together on the same chromosome and therefore can not be separated or mixed with other genes during shuffling that occurs in Meiosis1 metaphase and anaphase
Sex linked Genes
linked genes specifically on the X sex chromosome inhumane or the Z sex chromosome in birds and fish
chromosome theory of inheritance
The theory that chromosomes are linear sequences of genes. The unifying theory stating that inheritance patterns may be generally explained by assuming that genes are located in specific sites on chromosomes.
a graphic representation of the location of genes on a chromosome, based on correlating the genetic recombination results of testcrosses with the structural analysis of chromosomes that have undergone changes, such as deletions or translocations, as detected by banding techniques.
a mutation in which part of a chromosome or DNA is missing
The occurrence of a repeated section of genetic material in a chromosome
Duchenne muscular dystrophy
a form of muscular dystrophy. caused by a defective gene for dystrophin (a protein in the muscles).
a graphic representation of the arrangement of genes or DNA sequences on a chromosome
involves the exchange of genetic material either between multiple chromosomes or between different regions of the same chromosome
chromosome rearrangement in which a segment of a chromosome is reversed end to end.An inversion occurs when a single chromosome undergoes breakage and rearrangement within itself
map of chromosome based on recombinant % mapping data
genes that are inherited together with the other gene as they are located on the same chromosome
a measure of crossover frequency
a diploid cell missing a single chromosome
a failure for chromosomes or chromatids to separate during anaphase of mitosis or meiosis resulting in gametes with extra or missing chromosomes
3n, 4n 5n, multiple haploid sets of chromosome n or 2n is normal thus polyploidy is abnormal however many plants are known to be polyploid
an organism that contains a different combination of alleles from either of its parents
