If you needed to determine the order of genes on a chromosome,you should perform
A)a test cross.
B)a two-point cross.
C)a three-point cross.
D)a SNP test.

Question

Quizplus · Accepted Answer

A three-point cross involves crossing individuals heterozygous for three different alleles, which allows for the determination of the order and distance between genes on a chromosome. A test cross involves crossing with a homozygous recessive individual, which is useful for determining an unknown genotype. A two-point cross involves crossing individuals heterozygous for two different alleles, which can provide information about the linkage and distance between two genes, but may not be sufficient for determining the order of multiple genes on a chromosome. A SNP test involves analyzing single nucleotide polymorphisms and is not directly useful for determining gene order on a chromosome.
