Question

This tutorial will take you step-by-step through the question The locations of six dictions were mapped to the Drophila chro me as shown in the table. Recessive mutations (a,b,c,d, . and g) found in seven genes are known to be located in the same region as the dclctions, but the gene onder on the chromosome is not known. Multiple crosses are performed in which flics homozygous for one of the receive mutations are Crossed with flics that are homewygous for one of the deliction mutations. The phenotypes observed in the hororygous offspring ac summarized in the table. The symbol represents a mutant phenotype, and a plus sign (+) represents the wild-type phenotype Mutations TE Deletion + + + + Deletion 2 + + + Deletion 3 + + + + Deletion 4 + + + + Deletion 5 + + + + + Deletion 6 + + + Step 3: klentily in which deli cach mutant allcle is kocated. For each res mutation described, match all the deletion regions in which the recensive mutation is located Mutation Deletion(s) Anwer Bank

Answer 1

Organism which exhibit normal phenotype are Wild type whereas organism exhibiting a new phenotype as a result of mutation are known as Mutant type.

Mutant phenotype shows that something has occurred in the base sequence of gene which is results in a different or new type of sequence in the chromosome.
