Arecessive allele does not affect the phenotype of a heterozygous person. a. true b. false

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
