Question

as a result of the human genome project, a gene map of the entire human genome was produced. a gene map shows
a. the relative location of each known gene on a chromosome
b. the relative frequency of genes entering and leaving a population
c. the relative frequency of variations of genes within a population
d. the relative location of dna within the nucleus of each cell

Explanation:

基因图谱展示的是每条染色体上已知基因的相对位置。选项B是基因进入和离开种群的相对频率；选项C是种群内基因变异的相对频率；选项D是DNA在每个细胞细胞核中的相对位置，均不符合基因图谱的定义。

Answer:

A. the relative location of each known gene on a chromosome
