When Mendel crossed the P (parent) generation, what did
he call the generation
produced by the P
generation?
re
A. P2
B. F1
C. F2

B. F1

Explanation:

Plants used in first-generation crosses were called P, or parental generation, plants (Figure 8.3). Mendel collected the seeds produced by the P plants that resulted from each cross and grew them the following season. These offspring were called the F1, or the first filial (filial = daughter or son), generation.

answer: This means they are modified by size, shape, or function according to their purpose. Specialized cells make up tissues, tissues make up organs, and organs make up the systems that work together to make up our bodies. Nerve cells, blood cells, and reproductive cells are examples of specialized cells.
