(c) Based on the data in Table 1, describe why the dominant alleles for body color and wing shape are the alleles that produce a
Brrunno [24]

Answer:

Check the explanation

Explanation:

Consider the below table of F2 data of phenotypic flies: we can reconstruct the table as seen in the second attached image below:

From the above observations it is clear the Gray body long wings and Ebony body vestigial wings are the parental combinations and that the Gray body vestigial wings and Ebony body long wings are the recombinants.

Also the ratio indicates that Gray body is dominant over ebony body and that long wings is dominant over vestigial wings.

here the genes for the two characters have shown independent assortment which means that the genes are unlinked if located on the same chromosome or are located  on different chromosomes.

Now F1 hybrid= GgLl (G for Grey and L for Long)

Cross between F1 hybrid and true breeding Gray vestigial (GGll)

GgLl x GG ll

Gametes-----------> GL Gl gL gl Gl

        GL                          Gl                      gL                  gl

Gl    GGLl                      GGll                  GgLl               Ggll

   (Gray long)      (Gray vestigial)     (gray Long)     (Gray vestigial)

Therefore the probability of getting the flies with gray body vestigial wings= 2/4= 50%

b) The reason why the students obtained the above given F2 results involving a cross between true breeding Gray body and long wings with true breeding Ebony body and vestigial wings is that the genes for the two charcters asssort independently in F2 generation and that the genes are not linked as:

Parents------------------> GGLL x ggll

Gametes -----------------> GL gl

F1---------------------> GgLl (Gray long but in heterozous condition)

Now GgLl x GgLl

Gametes GL Gl gL gl   GL Gl gL gl

Here gametes assorted independently and hence in F2 generation we got the above results (U can show the results in the form of punnett square.

Which statement best describes the age of the seafloor?
Fittoniya [83]
The correct option is B. The newest crust on earth is located at the actual site of the floor spreading and as new crusts are formed they replace it. Thus, the older the crust the farther it is from the mid ocean ridge. 
Sea floor spreading is a geological process in which tectonic plates splits apart from one another. It occurs at divergent plate boundaries.

How is it possible that the F2 generation offspring had some short plants when the F1 generation had no short plants on Mendel's
sattari [20]
The f1 generation may have genes for short plants just that the genes for long plants are dominant over the genes for short plants(recessive) so when cross pollination happen and that two f1 long plants which are homozygous cross pollinate, the recessive genes have a chance of being paired up in new offspring(F2 offspring) thus the possiblity of short plants in f2 generation

Why do different cells within an individual organism function differently?
Maurinko [17]

Answer:

Explanation:

Because for example White blood cells which im pretty sure is Tcell if im not mistaken fight and the body from bacteria, theres a cell that clots at a wound and blood cells deliver oxygen through the body if all cells were to function the same way we all probaly wouldnt live but a few years in the slightest and there goes the human race GONE
