P F Yes 50 seeds--> 61 seeds so population growing by >20% / gen. 1. Does the population reproduce itself? No, This question is best answered by developing the concept of the gene pool. 2. Does each genotype reproduce itself? Gene pool = Abstract assemblage of all genes in a population. Gene Gene Frequency generation = 1 10/50 = 0.2 A generation = 2 4/61 = 0.06 10/50 = 0.2 B 9/61 = 0.15 10/50 = 0.2 C 8/61 = 0.13 10/50 = 0.2 D 20/61 = 0.33 10/50 = 0.2 E 20/61 = 0.33 G F P 10 B 9 SMALL 1 SEED /PLANT 9 4 2 SEEDS / PLANT 2 LARGE G F P 10 A SPRING SEEDS PHENOTYPE SUMMER PLANTS FECUNDITY
