In snapdragons, heterozygotes have pink flowers, whereas the dominant and recessive homozygotes have red and white flowers, respectively. When red-flowered plants are crossed with white-flowered plants, what percentage of the progeny will have pink flowers?

100%

Explanation:

We are given a red flower plant. This means its homozygous dominant (RR). We are given a white flower plant. This means it is homozygous recessive (rr). Each plant will give its allele. The red one will always give R and the white one will always give r. Heterozygous (Rr) plants have pink flowers. So they will all be pink.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
