Explanation / Answer

Ans 1) a & b
Explanation: The condition of two or more genes being located on the same chromosome whether or not there is a demonstrable linkage between them.
Linked genes are always syntenic , and they are always located near or one another on a chromosome.
The physical distance between two markers is measured with the number of nucleotides between them. If these markers are 1000 base apart, the physical distance will be 1000 nt. Physical distance can be measured with sequencing and counting the nucleotides.
Genetic distance is calculated according to the tendency of markers that are like together on a chromosome to be acquired together during the meiosis, phase of sexual reproduction. If markers are close together (small physical distance), they tend to inherited together. If markers are substantially inherited together, then the genetic distance will be less.
In real, genetic distance is highly connected with physical distance. As physical distance increases, the genetic distance is also raised.
Ans 2) c
Explanation: The "map unit" (1 cM) is the genetic map distance that corresponds to a recombination frequency of 1%.
Ans 3) c) Chromosome crossover: Homologous recombination of two chromatids while meiosis caused the alleles to shuffle, ending in a breakdown of the independent assortment of the alleles for those genes
Ans:4) a) 0.1
