Random genetic drift in a population probably results from
Large population size
Highly genetically variable individuals
Interbreeding within small isolated population
Constant low mutation rate
Which is basis of evolution
If frequency, of ' $A$ ' allele is $0.4$ than, find out the frequency of ' $B$ ' allele and heterozygous genotype in a random mating population at equilibria
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?
Which is the most common mechanism of genetic variation in the population of a sexually reproducing organism ?
In Hardy-Weinberg principle expression of allele frequency is represented by
