Hello, that is a very good question!
Back then there was no such thing as 'birth-control', hence they never actually prevented pregnancies, of course there were services that provided 'different' penetration but that could also result in pregnancies.
The popular method of not giving birth [prevent pregnancy] was to kill the baby while still carrying [termination], in other words have a miscarriage.
There many various methods during that time (herbs, beating, old cloth hanger).
Hope this helped,

The average human rate is 60 to 100 beats per minutes.
a) Evolutionary fitness can be characterized as a person's commitment to the cutting edge's quality pool,which is chiefly founded on the aggregate or the genotype of the individual.This principally identifies with the conceptive achievement of an organic entity.
It is fundamentally determined by the offspring that can endure and pass on the characteristics/traits.
b) Graph is already uploaded in the below attached document.
c) The population 3 will have the most elevated frequency of heterozygotes,45% of the complete population.
d) Since population 2 is as of now having a low number of heterozygotes, the occasion would totally eliminate them from the population or decreases their number
Explanation:
Frequency of animals in population 1 having both alleles 1 and 3
frequency of allele 1 =0.60
frequency of allele 3= 0.25
Frequency of both allele 1 and 3 would be allele 1 + allele 3 frequency x 100
= 0.60+0.25 X 100= 85%
