What is the function of BCSP31gene of Brucella organism?
What situations might be viewed as ethical uses of human cloning? Are you doubtful, fearful, or hopeful about human cloning?

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?
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?
A number of plant species have a recessive allele for albinism; homozygous albino (white) individuals are unable to synthesize chlorophyll. If a tobacco plant heterozygous for albinism is allowed to self-pollinate and 500 seeds germinate: a)how many offspring will be the same genotype as the parent? b)how many seedlings would you expect to be white?
A base deletion occurs in the regulator gene of the LAC operon. Describe how the operation of the LAC operon might be affected?

Is Genetic engineering the best of solution?
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?
If curly hair is genetic, why do you have curly hair if none of your ancestors did?
