The principle of dominance is derived from Mendel's conclusions. Which of the following describes the law of segregation? Some alleles of a gene are dominant, and others are recessive
If the recessive allele appears on one of the genes, the offspring will display the trait
Both dominant alleles need to be present for the offspring to inherit the dominant trait
Only 1
1, 2, and 3
2 and 3
1 and 2

Only 1

Explanation:

"Some alleles of a gene are dominant, and others are recessive" is the only true statement here. The other two, "If the recessive allele appears on one of the genes, the offspring will display the trait" and "Both dominant alleles need to be present for the offspring to inherit the dominant trait" can each be ruled out easily with the former being that both recessive alleles have to appear for the offspring to display the trait and the latter being that a dominant and a recessive can work with the dominant still showing.

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.

did you fail the test? xd
