Answer:

How many chromosomes would be found in an allopolyploid plant if its parents had diploid numbers of 4 and 6 respectively?

Diploid number of 10

Diploid number of 5

Haploid number of 12

Haploid number of 5

Answer:

Diploid number of 5

Explanation:

Gametes are formed by meiosis and have a haploid chromosome number. The parent with diploid chromosome number 4 would form gametes with haploid chromosome number 2. Similarly, the parent with diploid chromosome number 6 will form gametes having haploid chromosome number 3. The fusion of these gametes will result in a zygote having a diploid chromosome number 2 + 3 = 5. The fusion of haploid male gamete and haploid female gamete produces a zygote with diploid chromosome number.
