In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a). Another gene has a recessive allele wx t
hat results in waxy starch, as opposed to normal starch (Wx). The two genes segregate independently. An Aa WxWx plant is test crossed. What are the phenotypes and relative frequencies of offspring?
A <em>Aa WxWx </em>individual was test crossed (crossed with a homozygous recessive <em>aa wxwx</em> individual).
The homozygous recessive can only produce <em>a wx </em>gametes.
The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 <em>A Wx </em>and 1/2<em> a Wx </em>
<u>The possible offspring resulting from the combination of those gametes is:</u>
The aquatic organism such as fishes will adapt themselves to have strong fins so as to swim upstream against the current. * The aquatic plants will adapt themselves to grow on the rocks present in the stream. * They may adapt themselves to have a streamlined body that resist being washed downstream by the current.Answer:
Deforestation is a bad thing because it takes away homes from animals. It also ruins the earth. Trees and plants are important to the earth and we need them. They are used for food. Not only for us but for animals. They keep the air clean.
