Question

In order to assess recombination events between two markers, which two of the following must be known?

A Dominance/recessiveness of alleles
B Position of markers on chromosome
C Phase of marker alleles
D Allele frequencies
E Parents are heterozygous at both markers

Answer 1

To assess recombination events between two markers, the position of the markers on the chromosome and the phase of marker alleles must be known.

Step-by-step explanation:

In order to assess recombination events between two markers, the two things that must be known are the position of the markers on the chromosome and the phase of marker alleles.

By knowing the position of the markers on the chromosome, we can determine which genes are linked and how far apart they are. The phase of marker alleles refers to whether the markers are on the same chromosome and in the same orientation or on different chromosomes.
