Punnett square are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. a pansy that is homozygous for purple flowers (pp) is crossed with a pansy that is homozygous for pink flowers (pp). which genotypes will be included for the offspring in the punnett square for this cross?

When we cross PP x pp we obtain:

Pp + Pp + Pp + Pp (we obtain four identical genotype).

Pp (heterozygote flower) is the Only genotype when we cross two different homozygotes.

The phenotype will be the purple flower since it is the dominant genotype.

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.
