Tay-sachs disease is caused by a mutation in the hexa gene located on chromosome 15. tay-sachs follows an autosomal recessive pattern of inheritance. with the of the diagram, identify which of the offspring will be an unaffected carrier. a. a, b, and c b. b and c c. a and d d. a e. d

The unaffected carrier individual, is the one who has only mutated gene of the autosomal recessive disease.

The right answer is B and C individuals

The genes responsible for autosomal recessive (AR) transmitted diseases are localized on autosomes.

The mutated allele responsible for the disease is recessive on the wild allele; heterozygotes are healthy and the disease is expressed only in homozygotes.

Tay-Sachs disease is a neurodegenerative disease caused by a deficiency of hexosaminidase causing an accumulation of ganglioside GM2.

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
