Mendel's law of segregation states that organisms inherit two copies of each gene and that

Gene segregate

Explanation:

As per the Mendel's law of segregation, an organism that inherit two copies of each gene segregate at the time of cell division (gamete formation) in a way that each allele of a gene can combine with any other allele to form a new genotype during fertilisation stage.

For example a red color flower with genotype "RR" and a white color flower with genotpe "rr" segregate at the stage of gamete formation. Thus each "R" allele of red flower can combine with each "r" allele of white flower thereby producing heterozygous red flower with genotype "Rr" during fertilisation stage.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
