Answer:
the childcare and housework that women have to perform in addition to work outside the home is known as the second shift.
Explanation:
Unfortunately, it is still a human universal that women do the majority of housework in all countries. Harlie Hochschild has referred to this burden as "the second shift." In the author's interviews with research subjects, she found there was marital tension surrounding this issue in many couples and that women had a lack of sexual interest and were sleep deprived as a result. Hochschild also found that men in her study preferred the traditional role for women. Women should perform all the domestic work in their view. Women preferred an egalitarian arrangement where the housework and responsibilities with the children were shared.

I assume that the question here refers to the process of evolution. The "helpful variations" are small mutations that allow the organism to have a small advantage over other - and this organism can then pass this variation to its children better than other organisms, meaning that with time, more organisms will have it. This will accumulate over time and the percentage of organisms with this mutation will increase.
