In a sampled population the allelic frequency of recessive trait is $16\%$ then the allelic frequency of heterozygous individuals is

The age of fossils in the past was generally determined by the radiocarbon method and other methods involving radioactive elements found in the rocks.

Or

More precise methods, which were used recently and led to the revision of the evolutionary periods for different groups of organisms include:

For the $\mathrm{MN}$-blood group system, the frequencies of $\mathrm{M}$ and $\mathrm{N}$ alleles are $0.7$ and $0.3$, respectively. The expected frequency of $\mathrm{MN}-$blood group bearing organisms is likely to be:

A population of finch birds with medium sized beaks colonizes an island with plants producing medium and large sized seeds. After a disease wipes out all the plants with medium sized seeds, what is most likely to happen to the finches?

If in a population gene frequency of A is 0.1 the frequency of allele 'a' will be _____.

Which one of the following is an essential condition for a population to be at Hardy-Weinberg equilibrium?

The common morning glory (Ipomoea purpurea) exhibits two flower colours, where purple is dominant over pink. Within a population of common morning glory which is at genetic equilibrium, $9\%$ of all flowers are pink. Assuming that there are no other compounding factors, what is the frequency of flowers in the population that are heterozygous?

If the allele frequency of 'A' is 0.2 the frequency of allele 'a' will be-
