To determine if a particular plant is homozygous or heterozygous, you would have to test cross with a to make the check.
homozygous recessive
heterozygous dominant
homozygous dominant
purebred

Homozygous recessive

Explanation:

Diploid (2n) organisms possess two alleles for a specific gene in which one of the allele can mask the expression of another in that gene. The allele that masks the expression of the other is said to be the dominant allele while the allele that is masked is the recessive allele.

The genotype of an individual is the genetic make-up while the phenotype is the expressed trait. Since, an allele can mask the expression of another, it is therefore impossible to ascertain the genotype of an organism by merely looking at its phenotype. The organism can either be homozygous (TT) or heterozygous (Tt) for that trait

N.B: T represents dominant allele of the gene coding for height, and t represents the recessive allele of the same gene

To determine whether an organism showcasing a dominant trait is homozygous or heterozygous for a specific allele, a TEST CROSS is conducted by crossing that organism with an organism with homozygous recessive trait.

N.B: An organism can only exhibit recessive traits if the alleles are homozygous ( same recessive alleles).

If all the offsprings of the cross showcase dominant traits, it means the parent organism is homozygous dominant but if any of the offsprings exhibit recessive traits, it means the parent organism is heterozygous dominant.

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.

answer: i feel like it would be 3
