A horticulturalist wants to produce geraniums with specific characteristics.

She knows that the trait of red flowers is governed by the allele R (RR and Rr) and the trait of white flowers is governed by the allele r(rr) .

The horticulturalist crosses two geraniums from the F1 generation.

Look at the Punnett square to see this cross.
R r
R RR Rr
r Rr rr

Which ratio of red-to-white flowering plants would she expect to see in the phenotypes of the F2 generation?

all red

2 red : 2 white

3 red : 1 white

1 red : 3 white

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.

the correct answer was location c, because earth is tilted away from the sun at this time
