The right option is; Turns litmus paper red

Turns litmus paper red is the description that is not a property of a base.

A base is any water soluble substance that have a bitter taste, slippery to the touch, and a pH that is higher than 7. Bases react with acids to produce salts, and promote specific chemical reactions. Bases change the colour of indicators (such as it turns red litmus paper blue). Examples of bases include limewater, bleaches, soaps and ammonia water.

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

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%
