The fur color gene is located on the " X" chromosome.

毛色基因位于 X 染色体上。

That's the allele frequency of the tomato color gene in that population.

这就是这个群体中番茄颜色基因的等位基因频率。

The male " Y" chromosome, on the other hand, does not have any color genes.

另一方面，公猫的 Y 染色体没有任何颜色基因。

Maybe a mutation happens in the tomato color gene that creates a third allele, c-prime, that produces white tomatoes when they inherit two c-primes, just like how two little c's yield yellow tomatoes.

也许番茄颜色基因发生了突变，产生了第三个等位基——c '，当遗传两个 c ' 时，就会产生白色番茄，就像两个小 c 产生黄色番茄一样。

Like, if a flock of birds feast on tomatoes from a distant population — ones with different color gene alleles — they might poop out those seeds as they fly over our tomatoes.

比如，如果一群鸟吃了来自遥远种群的西红柿——那些有着不同颜色基因等位基因的西红柿——它们飞过我们的西红柿时可能会把那些种子拉出来。
