That means the alleles, or gene versions, already together on one chromosome will be inherited as a unit more frequently than not. We can see if two genes are linked, and how tightly, by using data from genetic crosses to calculate the recombination frequency. WebTwo copies of chromosome 1, one copy inherited from each parent, form one of the pairs. Chromosome 1 is the largest human chromosome, spanning about 249 million DNA building blocks (base pairs) and representing approximately 8 percent of the total DNA in cells.
