Answer

Brief Explanations:

Let the allele for cleft - chin be (C) (dominant) and for no - cleft be (c) (recessive). True - breeding parents are (CC) (cleft - chin) and (cc) (no - cleft). The (P) generation has one parent with a cleft chin ((CC)) and one with no cleft ((cc)). When crossed ((CC\times cc)), all (F_1) generation offspring will be (Cc) (cleft - chin because of the dominant allele). When (F_1) generation ((Cc\times Cc)) is self - crossed, the (F_2) generation has a genotypic ratio of (1CC:2Cc:1cc), so there will be both cleft - chin ((CC) and (Cc)) and no - cleft ((cc)) individuals.

Answer:

The (F_1) generation will have all cleft chins. The (P) generation and (F_2) generation will have cleft chins and no - cleft chins.
