What type of inheritance is expressed when the following allele combinations express the given phenotypes: R is dominant for red and r is recessive for white. The genotypes RR and Rr both express the phenotype red. The genotype rr expresses the phenotype white. A) Incomplete Dominance B) Polygenic trait C) Epistasis D) Multiple Alleles E) Codominance F)Mendelian Genetics (Complete dominance)

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
