Male turkeys have a snood, which is a flap of skin that hangs across their beak. Snood length is negatively correlated with parasite load (e. g., males with longer snoods have fewer parasites), and females prefer to mate with long-snooded males. The snood is an example of:

In a classic experiment using pea shape, mendel conducted two separate genetic crosses. in the first cross the parent plants were “true breeding” for pea shape; one had round peas ( r )and the other had wrinkled (r). the first cross produced a filial 1 generation of all round peas. in the second cross, mendel bred plants from the filial 1 generation. this cross produced different results. out of approximately 1000 plants, about 75% were round and 25% were wrinkled.

Mitosis creates two identical daughter cells from one parent cell creates four nonidentical daughter cells from one parent cell is the most common type of reproduction for bacteria is the process by which male and female reproductive cells are created
