A researcher is studying the color of grasshopper exoskeletons. Assume that this phenotype is caused by the action of two alleles. Green grasshoppers have the genotype AA and brown grasshoppers have the genotype aa. If the frequency of the A allele in this population is 0.2, what is the frequency of the a allele

What is the difference between self-pollination and cross-pollination? question 2 options: self-pollination leads to the creation of a fruit. cross-pollination does not. during cross-pollination, ovules are carried from one plant to another plant.. during self-pollination the ovules stay on the same plant. during cross-pollination, ovules are carried from one plant to another plant.. during self-pollination the ovules stay on the same plant. during cross-pollination the pollen grains are carried from one plant to another plant. during self-pollination the pollen and ovules are from the same plant. during cross-pollination, the pollen grains travel from the stigma to the anthers. during self-pollination, the pollen grains travel from the anthers to the stigma.

Which of the following represents a negatively charged ion? of t 7

Parthenogenesis is a type of reproduction that does not require a mate. it’s rarely seen in birds and higher vertebrates. parthenogenesis involves the formation of a zygote. but this zygote is formed without fertilization. in parthenogenesis, in the absence of a male gamete, the ovum develops directly in the zygote.
