Answer:26
Explanation:To determine the number of chromosomes in an allotriploid resulting from species a and species b, we start by understanding their chromosome counts:
Species a has
2
=
14
2n=14 chromosomes, so
=
7
n=7.
Species b has
2
=
12
2n=12 chromosomes, so
=
6
n=6.
An allotriploid would contain two sets of chromosomes from one species and one set from the other species. Let's calculate the total number of chromosomes in an allotriploid:
Two sets from species a:
2
×
7
=
14
2×7=14 chromosomes.
One set from species b:
1
×
12
=
12
1×12=12 chromosomes.
Therefore, the total number of chromosomes in the allotriploid would be
14
+
12
=
26
14+12=26
