Comparisons of neanderthal dna revealed that there are more similarities to non-african dna than reference sequences from west africans. Additionally, scientists found that neanderthal dna is as closely related to east asians as to europeans. This indicates that interbreeding occurred before human migration further east. What process of population genetics generated these results?.

In a classic experiment using pea shape, mendel conducted two separate genetic crosses. in the first cross the parent plants were “true breeding” for pea shape; one had round peas ( r )and the other had wrinkled (r). the first cross produced a filial 1 generation of all round peas. in the second cross, mendel bred plants from the filial 1 generation. this cross produced different results. out of approximately 1000 plants, about 75% were round and 25% were wrinkled.
