G If an organism expresses the dominant phenotype, . A) it is homozygous dominant B) it cannot produce offspring with the recessive phenotype C) it carries two of the same dominant alleles D) it may carry a recessive allele

D) it may carry a recessive allele

Explanation: An allele is the alternative form of a gene. An a gene is the functional unit of DNA.

Each organism has a genotype and it is made up of allele of the individual gene.

Homozygous means allele of a genotype are the same AA

Heterozygous means the individual has two different allele example is Aa.

An individual can either be homozgous dominant or heterozygous dominant depending on the allele of the genotype. If an individual is dominant of a particular trait it could either be homozygous or heterozygous.

If an individual is heterozygous of a particular traits it could contain an allele that is recessive whose effect could have been masked by the other allele that is dominant example is when we have complete dominance considering Aa where allele A is dominant over allele a and the individual expresses a phenotype of allele A and a is reccessive.
