If new combinations of two different traits appear in offspring, which Mendelian idea is supported?
Answer and explanation
Correct answer: Independent assortment of alleles for different traits.
When offspring display combinations of traits that were not present together in the parents, the hereditary factors for the two traits are not being transmitted as one inseparable package. During gamete formation, allele pairs for different traits can assort independently and then recombine during fertilisation. This is Mendel’s law of independent assortment, so option A is correct. The other choices concern unrelated or scientifically unsupported ideas.
