Answer:
i'd recommend rereading it
Explanation:
The answer is E) <span>9 sharp-spined:3 dull-spined:4 spineless.
It is known that the in </span><span>dihybrid</span> cross (a cross between two different traits), the phenotypic ratio between the offspring in the F2 generation is 9:3:3:1<span>:
9 - individuals with both dominant traits (SSNN),
3 - individuals with the first dominant trait and the second recessive trait (SSnn),
3 - </span><span>individuals with the first recessive trait and the first recessive trait (ssNN),
</span><span>1 - individual with both recessive traits (ssnn).
According to this, there will be 9 sharp-spined cactuses (SSNN), 3 dull-spined cactuses (ssNN), and 4 spineless cactuses (3 cactuses with SSnn genotype and 1 cactus with ssnn genotype).
