Final answer:
Linkage analysis is the method used to assess the likelihood that two traits are genetically linked by analyzing pedigrees to see if the traits are inherited together.
Step-by-step explanation:
The type of analysis that assesses the likelihood that two traits are genetically linked by creating pedigrees to analyze both traits simultaneously is b. Linkage analysis. Linkage analysis studies the recombination frequency between any two genes, which helps to determine if the genes are linked and, therefore, likely to be inherited together.
This form of analysis is foundational in the creation of genetic maps, and it relies on understanding the patterns of inheritance depicted in pedigrees as well as on actual biological processes such as genetic recombination, which includes crossing over events between nonsister chromatids during meiosis.
