Genotype ratio refers to the probability of each type of thing (in this case, round/yellow seeds) occurring based on the Punnett square. If you were to write out how many of each specific hybrid occurred in the square, you'd get:
1 RRYY
2 RRYy
2 RrYY
4 RrYy
1 RRyy
1 rrYY
1 rryy
What does this tell us? In this case, the only thing that matters is the capital letter (since that's the dominant trait and will determine whether the seed is/isn't round/yellow).
Looking at each one, you see some of them are the same - for example, RRYY and RRYy both end up as round and yellow. RrYy is too, as is RrYY.
So, you end up with 9 round and yellow; 3 round and not yellow; 3 not round and yellow; 1 not round and not yellow.
Answer: Possibly increase the production of socks
Explanation: As it implies, the mosquitoes that have sickness land on socks more often. Based on this information, since we know that malaria comes from mosquitoes, we can increase the production of socks, as that will separate most of the infected mosquitoes with the other mosquitoes, as most of the infected ones will fly over to the sock. With this scenario, we can bait the mosquitoes and know which ones are infected
