Genetic drift refers to the change in the relative frequency of distinct genotypes in a small population, owing to the chance vanishing of specific genes as individuals do not reproduce or die. In the given case A, the population included 500 individuals of females and males in which the males compete heavily with the females for harems. In the given situation, the females give birth to one offspring in each season. In the case of B, the population includes just 250 individuals, and in this, the mating bond between the females and males goes through the mating season. In the given case, the females on an average give rise to 3 to 4 offsprings in a season.

A population of horses in the magic land is having a problem. Individuals are not mating randomly and they are only mating with those that have the same flying speed as their own: Fast (FF), Medium speed (FS), or Slow (SS). You arrive to this magical land and count the following horses of each flying velocity: Fast = 71 Medium speed = 90 Slow = 31 If we consider these results Generation 1, what are the expected number of Medium speed individuals for each genotype in Generation 3 if we have only inbreeding, that is, FF only reproduces with FF; FS only reproduces with FS; and SS only reproduces with SS?

Johnston et al. estimate that 50% of males with the Ho Ho genotype develop scurs (instead of full horns). They also estimate that around 13% of the total male population, at birth, will develop scurs. The males who managed to get access to mating opportunities with females seem to show no preference for whether the females have horns or not. Thus in the adult mating population, mating is random with respect to the genotype at this locus. What is the frequency of the Hop allele in the population?

Which of the following statements is true about certainty of paternity? Question 12 options: Certainty of paternity is low when egg laying and mating occur together, as in external fertilisation. Certainty of paternity is high in most species with internal fertilisation because the acts of mating and birth are separated by time. Certainty of paternity is low when males guard females they have mated. Paternal behaviour exists because it has been reinforced over generations by natural selection
