These are specific sequences in DNA of all
oranisms ,viruses which can get inserted to any other DNA.
So called as jumping genes discovered by by Barbara Mc
clintosh.They may be replicative /non replicative.They are
classified as composite ,Is Cut &paste .Retroposons
etc.They bring about mutation (frame shift )& also
oncogenic .some of the egs are LINES ,SINES In humans ,gal
genes in drosophila

Cystic fibrosis (CF) occurs with a frequency of about 1/2500 Caucasian newborns and is inherited as an autosomal recessive. A woman had an older sister die from complications of this disease. CF is not present among relatives of her husband. Both the woman and her husband have normal phenotypes. What is the chance this couple will have a CF child
A blastomere was removed from an 8-cell human embryo, and its beta-globin gene was amplified by PCR. The beta-globin DNA was treated with an enzyme that cuts on either side of and within the normal allele (producing a small fragment), but not within the sickle cell allele (producing a large fragment). Electrophoresis of the treated DNA from the blastomere demonstrated the presence of both a large and small fragment derived from the beta-globin genes. How should you interpret this test?

If curly hair is genetic, why do you have curly hair if none of your ancestors did?
The ABO blood system has been employed to settle cases of disputed paternity. Suppose, as an expert in genetics, you are called to testify in a case where the mother is type A, the child is type O and the alleged father is type B. How would you respond to the following statements of the attornies: a. "Since the mother has type A, the type O of the child must have come from the father and since my client is type B, he obviously could not have fatered the child." Made by the attorney of the alleged father. b. "Further tests revealed that this man is heterozygous and therefore he must be the father." Made by the mother's attorney.
Does a person diagnosed with turner syndrome have trouble hearing? please reply if you have this syndrome or know someone who does.
In cucumbers normal leaves (N) are dominant to curled leaves (n) and elongated fruit (L) is dominant to spherical fruit and these genes are linked on the same chromosome. If a pure-breeding normal-leaved, elongated fruit cucumber is crossed with a curled-leaved, spherical fruit cucumber, what will be the phenotype of the F1? the phenotypic ratio of the F2?
How will you differentiate alleles of a gene in the double strand of DNA?
In cats yellow is due to gene B and black to its allele b. These genes are located on the X chromosome (sex-linked). The heterozygous results in calico (tortoise shell). What kinds of offspring (sex & color) are expected from the cross: black male & calico female? Most calico males are sterile, why?
The village of Oblong has 400 normally-shaped residents. Transferrin is an iron carrier found in blood, and electrophoretic variation of this protein is determined by an autosomal codominant system. The citizens of Oblong were typed for their transferrin complements. The distribution of transferrin phenotypes was: 100 CC, 100 CD, and 200 DD. What is the frequency of the C allele?
Consider two linked autosomal genes. The dominant allele C of the first gene causes cataracts of the eye, whereas its recessive allele produces normal eyes. The dominant allele P causes polydactyly (an extra finger) whereas its allele (p) produces a normal number of fingers. A man with cataracts and normal fingers marries a woman with polydactyly and normal eyes. Their son has both polydactyly and cataracts and he marries a woman with neither trait. What is the probability that their first child will have cataracts and polydactyly?
