A female carrier of Tay-Sachs wants to have a child with a male carrier for Tay-Sachs. Tay- Sachs is inherited in an autosomal recessive manner. Using the letters \"T\" and T fill out the following table. Solution Autosomal recessive conditions are associated with non sex chromosomes and the disease allele must be present in homozygous condition to inflict the disease. Tay-Sachs is a sphingolipidoses associated with mutation in the HEXA gene situated on the chromosome 15. A defective copy of both the allele for HEXA gene will lead to Tay sachs. Lets say that the wild type HEXA gene is T and defective gene is t. genotype of Mother - Tt; phenotype of mother- carrier genotype of father-Tt; phenotype of father- carrier Cross between the two: Parents: Tt X Tt offsprings: TT; Tt; Tt; ttFemaleMaleGenotypeTT; Tt; Tt; ttTT; Tt; Tt; ttPhenotypeNormal; carrier; carrier; affectedNormal; carrier; carrier; affectedGenotypes of sperm/ovaSame as the individualsame as the individual.
