A population will not exist in Hardy-Weinberg equilibrium if
there is no migration
the population is large
individuals mate selectively
there are no mutations.
In a certain population, the frequency of three genotypes is as follows
Genotypes : | $BB$ | $Bb$ | $bb$ |
frequency : | $22\%$ | $62\%$ | $16\%$ |
What is the likely frequency of $B$ and $b$ alleles ?
In a species, the weight of newborn ranges from $2$ to $5\; \mathrm{kg} .97 \%$ of the newbom with an average weight between $3$ to $3.3\; \mathrm{kg}$ survive whereas $99 \%$ of the infants born with weights from $2$ to $2.5\; \mathrm{kg}$ or $4.5$ to $5 \;kg$ die. Which type of selection process is taking place?
Organic evolution would have not been taken place
The tendency of population to remain in genetic equilibrium may be disturbed by
Among the five factors that are known to affect Hardy-Weinberg equilibrium, three factors are gene flow, genetic drift and genetic recombination. What are the other two factors ?
