True breeding brown dogs with genotype aabb were cross to true breeding white dogs with genotype AABB. All F1 offspring having white phenotype were allowed to intercross to produce F2 progeny as following number –

A- - - 118 white,

aa B- 32 black

aa bb 10 brown

A Male Dog with AaBb genotype was cross with female dog with aabb genotype. What is probability of Black phenotype among their offspring if A gene link B gene at 10 map unit at cis configuration?

With respect to microRNAs, which, if any, of the following statements, is false?

a) A microRNA normally works by binding to perfectly complementary sequences within an RNA transcript, usually an mRNA.

b) Like the great majority of mRNAs an miRNA is usually produced as a larger precursor RNA that is capped and has a 3’ poly(A) tail.

c) The precursor miRNA undergoes different types of post-transcriptional cleavage by endoribonucleases that are specific for double-stranded target sequences.

d) A nuclear endoribonuclease called dicer cleaves the miRNA precursor so that it forms a stem-loop RNA.
