If the husband is $R{h}^{*}$ and the wife is $R{h}^{-}$.

In Escherichia coli how many codons code for the standard amino acid?

What is the number of chromosomes in an individual with Turner's syndrome?

A breeder crossed a purebred tall having white flowers to a pure bred short plant having blue flowers. He obtained $202 {\mathrm{F}}_1$, progeny and found that they are all tall having white flowers. Upon selfing selfing these ${\mathrm{F}}_1$ plants, he obtained a progeny of $2160$ plants. Approximately, how many of these are likely to be short and having blue flowers?

A human population containing $200$ individuals has two alleles at the $‘\mathrm{T}’$ locus, named $\mathrm{T}$ & $\mathrm{t}$. $\mathrm{T}$ which produces tall individuals, is dominant over $\mathrm{t}$, which produces short individuals. If the population has $90\mathrm{TT}, 40\mathrm{Tt}$ and $70\mathrm{tt}$ genotypes, what will be the frequencies of these two alleles in this population?

An mRNA is transcribed from a DNA segment having the base sequence $3^{\text{'}}-\mathrm{TACATGGGTCCG}-5^{\text{'}}$. What will be the correct order of binding of the four amino acyl-tRNA complexes given below translation of this mRNA?

If the initial number of template DNA molecules in a PCR reaction is $1000$, the number of product DNA molecules at the end of $20$ cycles will be closest to

The allele for black hair (B) is dominant over brown hair (b) and the allele for the brown eye (E) is dominant over the blue eye (e). Out of the offsprings obtained upon mating a black-haired and brown-eyed individual (BbEe) with a brown-haired and brown-eyed individual (bbEE), the ratio of brown-haired and brown-eyed individuals to black-haired and brown-eyed individuals is
