In parakeets, two autosomal genes (located on different chromosomes) control the production of feather pigments. Gene B controls the production of blue pigment, and gene Y controls the production of yellow pigment. Known recessive mutations in each gene result in the loss of pigment synthesis. Two green parakeets are mated […]

Q. 1. Alleles might be explained as: a. similar forms of two different loci b. alike forms of two different genes c. Alternative forms of a single gene d. Alternative forms of two different loci 2. A mutation which produces a change from wild type to an abnormal phenotype is […]

Question: The OMIM description on “Genetic Mapping of Alkaptonuria” can be interpreted to say: The alkaptonuria gene was genetically mapped to 3q2 at 16cM away from the sucrase-isomaltast deficiency gene in inbred families with some members manifesting both conditions. Statistically the alkaptonuria causing mutant gene and the sucrase-isomaltase deficiency-causing mutant gene […]
