In tomato plants, the allele for purple stems is dominant to allele for green stems and the allele for red fruit is dominant to

Kamila [148]

So let's call the allele that is dominant for purple stems is P, and the recessive allele yielding green stems is p. And let's say that the allele that is dominant for red fruit is R and the recessive allele for yellow fruit is r.

The two plants are each heterozygour for both traits, meaning that the cross is going to be:

PpRr x PpRr

So let's setup a Punnet Square:

$\left[\begin{array}{ccccc}&PR&Pr&pR&pr&PR&PPRR&PPRr&PpRR\4&PpRr&Pr&PPRr&PPrr&PpRr&Pprr\\pR&PpRR&PpRr&ppRR&ppRr&pr&PpRr&Pprr&ppRr&pprr\end{array}\right]$

The genotypic ratios (alleles) and phenotypic ratios are as follows:

PPRR (Purple stem, Red fruit): $\frac{1}{16}$

PpRR (Purple stem, Red fruit): $\frac{2}{16}$ or $\frac{1}{8}$

ppRR (Green Stem, Red fruit): $\frac{1}{16}$

PPRr (Purple stem, Red fruit): $\frac{2}{16}$ or $\frac{1}{8}$

PPrr (Purple stem, Yellow fruit): $\frac{1}{16}$

PpRr (Purple stem, Red fruit): $\frac{4}{16}$ or $\frac{1}{4}$

pprr (Green stem, Yellow fruit): $\frac{1}{16}$

ppRr (Green stem, Red fruit): $\frac{2}{16}$ or $\frac{1}{8}$

Pprr (Purple stem, Yellow fruit): $\frac{2}{16}$ or $\frac{1}{8}$

So then we take the like phenotypic ratios and add them together:

Purple stem, Red fruit: $\frac{1}{16} +\frac{2}{16} +\frac{2}{16} +\frac{4}{16}=\frac{9}{16}$

Green stem, Red fruit: $\frac{1}{16}+ \frac{2}{16} =\frac{3}{16}$

Purple stem, Yellow fruit: $\frac{1}{16}+ \frac{2}{16} =\frac{3}{16}$

Green stem, Yellow fruit: $\frac{1}{16}$

Explain why Hurricane Harvey traveled from the east (Africa) towards the west (Florida) when our weather in Wisconsin starts in

sergiy2304 [10]

Answer:

Due presence of Sahara desert that is responsible for the formation of this hurricane and its movement towards Florida.

Explanation:

Hurricane Harvey traveled from the Africa towards the Florida because these hurricane formed at the African region due to the presence of Sahara desert. The hot and dry wind of Sahara desert meets with the cool, moist air from the south produces these hurricane which then moves from the Africa to the west side where Florida is located so that's why Hurricane Harvey traveled from Africa towards the Florida.
