Chilopoda. Centipedes.
Crustacea. (crabs, lobsters, shrimp.
Diplopoda. Millipedes.
Hexapoda. Insects.
so your answer will be mollusks
Reading background information because it gives ideas from the author himself.
The genotypes A B_, A bb, aaB_, and aabb are matched to the four phenotypic groups.
<h3>How do phenotypic classifications work?</h3>
The genotypes A B_, A bb, aaB_, and aabb are matched to the four phenotypic groups. If any of the single homozygous recessive genotypes (i.e., A bb or aaB_) exhibits the same phenotype as the double homozygous recessive (aabb), then a 9:3:4 phenotypic ratio will result.
<h3>What does phenotypic classification entail?</h3>
phenotype, all of an organism's observable traits that emerge from the interaction of its genotype (total genetic inheritance) and environment. Observable features include things like behavior, biological characteristics, colour, shape, and size.

Answer: 0.18
Explanation:
For the alleles, the percentage distribution of each is 'A' (90% = 0.9)
While 'a' (10% = 0.1)
Hence, 0.9 and 0.1 are the respective frequencies of each allele
Now, apply Hardy-Weinberg Equilibrium equation, where heterozygotes are represented by the 2pq term.
Therefore, the number of heterozygous individuals (Aa) is equal to 2pq which equals
2 × 0.9 × 0.1 = 0.18
Thus, the frequency of heterozygote is 0.18, while the percentage distribution in the population is 18%
