PATHOLOGY

Detailed explanation-1: -organism whose genome contains a gene for a certain trait or disease that is not expressed in the organism’s phenotype. heterozygous genotype that equally expresses the traits from both alleles. heterozygous phenotype that is a blend of the two homozygous phenotypes.

Detailed explanation-2: -Heterozygous refers to having different alleles for a particular trait. If the two versions are different, you have a heterozygous genotype for that gene.

Detailed explanation-3: -Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.

Detailed explanation-4: -Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.

Detailed explanation-5: -An allele that is not expressed in the heterozygous condition is (d) recessive. Each variation of a gene sequence is an allele. If an allele is not expressed in an individual heterozygous for that gene, the allele is considered to be recessive.
