Understanding

Which of the following statements is true about linked genes?

• They are located on the same chromosome and inherited as a single unit

• They undergo independent assortment during meiosis

• They are always found on different chromosomes

• They have a high frequency of recombination

Applying

What is the purpose of using a chi-squared test in genetic studies?

• To determine if observed data fits expected ratios

• To identify the specific locus of a gene

• To calculate the frequency of recombination

• To predict the outcome of a monohybrid cross
