6. linkage analyses using crosses or matings (just like y, f, cv from your biol311 nightmares…) or family pedigree analyses are two methods used in mapping techniques. a. cdna b. expression c. genetic d. physical

Answer is C..Genetic.

Explanation:

Genetic mapping which is also known as linkage mapping is a reliable way to know and identify which exact chromosome has which gene, also showing exact place where the gene lies on the chromosome.

The genetic mapping is useful in giving firm evidence that a disease that is being transmitted from parents to children is associated to one or more genes.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
