NEET BIOLOGY

Detailed explanation-1: -In one sense, the term “genotype”-like the term “genome”-refers to the entire set of genes in the cells of an organism. In a narrower sense, however, it can refer to different alleles, or variant forms of a gene, for particular traits, or characteristics.

Detailed explanation-2: -An individual’s genotype is the combination of alleles that they possess for a specific gene. An individual’s phenotype is the combination of their observable characteristics or traits. While an organism’s genotype is directly inherited from its parents, phenotype is merely influenced by genotype.

Detailed explanation-3: -For an organism to be a carrier, the genotype must include one copy of a recessive allele. Carriers do not exhibit the physical trait, but have a 50 percent chance of passing the gene on to an offspring.

Detailed explanation-4: -In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.

Detailed explanation-5: -Genotype AA is the universally compatible genotype that is, regardless of who they partner up with, there is no possibility of them birthing a child with sickle cell disease. Here are the compatible and incompatible genotypes: AA + AA = compatible. AA + AS = compatible. AA + SS = compatible.
