Choose two correct answers What gametes are formed in the first generation hybrids: 1. hybrid 2. non-hybrid 3 mixed 4. clean 5. Choose the correct answer Where are the genes of paired traits in dihybrid crossing: 1. in one chromosome 2. in homologous chromosomes 3. in different pairs of chromosomes 6. Choose two correct answers. Where are nonallelic genes: 1. in one chromosome 2. in homologous chromosomes 3. in different pairs of chromosomes 7. Choose two correct answers The law of purity of gametes says: 1. The gametes contain one pair of allelic genes 2. gametes contain two pairs of allelic genes 3. gametes contain one gene from each allelic pair 4. in a heterozygote the genes do not mix with each other 8.

Genes localized in one chromosome are: 1. alternative 2. allelic 3. clutch group
