One of the possible effects of increased carbon dioxide concentration on our planet would be a warmer climate.

<h3>Greenhouse effect</h3>

Carbon dioxide is one of the numerous greenhouse gases that exist in nature. The gases are responsible for the warming of the planet.

Carbon dioxide and other greenhouse gases form a blanket layer in the atmosphere and trap some of the reflected solar radiations from the sun, preventing them from escaping back to space.

The more the concentration of greenhouse gases in the atmosphere, the more the solar radiation that is trapped and the warmer the earth gets.

In fruit flies, the gene for red eyes (R) is dominant and the gene for sepia eyes (r) is recessive. If a red-eyed heterozygous f

ladessa [460]

The answer is Rr and rr.

We know:
r - recessive allele
R - dominant allele
RR - dominant homozygote with red eyes
Rr - heterozygote with red eyes (since one dominant allele R can mask recessive allele r)
rr - recessive homozygote with sepia eyes

Heterozygote Rr can give to the offspring either dominant allele R or recessive allele r. Recessive homozygote rr can give to the offspring only recessive allele r (take a look at the uploaded image of Punnett square).
After crossing the parents:
Parents: Rr x rr
Offspring: Rr rr Rr rr

So:
2 out of 4 offspring will be with heterozygous with red eyes Rr: 2/4 = 0.5 = 50%
2 out of 4 offspring will be with homozygous with sepia eyes rr: 2/4 = 0.5 = 50%
