The explanation about the generation of the stable and unstable ct + revertants and stronger ct mutant alleles. Introduction: A mutation in the Drosophila cut wing ( ct ) gene known as ct MR2 , is responsible for the insertion of a transposable element known as gypsy . Some of the progeny of flies bearing the ct MR2 gene become revertants. When these revertants are mated, some of the alleles become stable, whereas others become highly unstable.

The explanation about the generation of the stable and unstable ct⁺ revertants and stronger ct mutant alleles.

Introduction:

A mutation in the Drosophila cut wing (ct) gene known as ct^MR2, is responsible for the insertion of a transposable element known as gypsy. Some of the progeny of flies bearing the ct^MR2 gene become revertants. When these revertants are mated, some of the alleles become stable, whereas others become highly unstable.

Suppose a researcher has three different Drosophila strains that have mutations in the bicoid gene called bicoid-A, bicoid-B, and bicoid-C; the wild type is designated bicoid +. To study these mutations, phenotypically normal female flies that are homozygous for the given bicoid mutation were obtained, and their oocytes were analyzed using a Northern blot to determine the size and/or amount of the bicoid mRNA and in situ hybridization to determine the bicoid mRNA location within the oocyte. A wild-type strain was also analyzed as a control. In both cases, the probe was complementary to the bicoid mRNA and the results are shown below. (Anterior is on the left; posterior is on the right.)

Leber Congenital Amaurosis (LCA) causes progressive vision loss due to defects in the gene that encodes RPE65 isomerase. Affected individuals are homozygous recessive for mutant alleles of the RPE65 gene. You are trying to determine the molecular nature of the mutations in three individuals with LCA. For ease of analysis, you may assume that each individual is homozygous for the same mutant allele (though the three individuals have different mutations than each other). You use the polymerase chain reaction to amplify DNA from each patient and you determine the sequence of the DNA and compare it to unaffected individuals. You identify the following differences. Note that the non-template strand of DNA is given and the changes are highlighted using red boldface. You can assume that the sequences are in the first reading frame (eg. the first three nucleotides of each sequence is a codon). The coding region of the gene is 1602 bp and the position of the sequences shown below is…

When a female melanotic fly is crossed with a normal male, the progeny are produced: 123 normal females, 125 melanotic females, and 124 normal males. In subsequent crosses between melanotic females and normal males, melanotic females are frequently obtained, but never any melanotic males. Provide a possible explanation for the inhertiacne of the melanotic mutation (Hint: The cross produces twice as many female progeny as male progeny)
