In humans, brown eyes (B) are dominant over blue (b)*. A brown-eyed man marries a blue-eyed woman and they have three children, two of whom are brown-eyed and one
of whom is blue-eyed. ("Actually, the situation is complicated by the fact that there is more
than one gene involved in eye color, but for this example, we'll consider only this one gene.)
1. A) If blue is recessive, what must the woman's genotype be?
1. B) If the man has brown eyes, but has a blue-eyed child what must his genotype
be?
or
1. C) If that's his genotype, what kind(s) of gametes (sperm) can he produce?

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.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
