Answer 1

Q28)

• Far from

Genes that are close by on the same chromosome are said linked. However, genes on the same chromosome but far apart may appear to be unlinked.

Q29)

• 50%

50% of F2 offspring had a parental phenotype.

Q30)

• Independent assortment

Since the Dihybrid parent (AaBb), produces the AB, Ab, aB, and ab gametes in equal proportions, the Genes are asserting independently.
