grandymaker [24]

Answer:

                Total Pieces      Food Percentage   Simulated Number of Birds

              of Food Eaten                                      in Flock for 2nd Generation

Flock X          57                            19%                                 6

Flock Y          153                           51%                                15

Flock Z         90                            30%                                9

<u>Calculations. </u>

Food percentage:

Flock X = 57/300 * 100% = 19%

Flock Y = 153/300 * 100% = 51%

Flock Z = 90/300 * 100% = 30%

Simulated Number of Birds in Flock for 2nd Generation

Flock X = 19% * 30 = 6

Flock Y = 51% * 30 = 15

Flock Z = 30% * 30 = 9

jolli1 [7]
For this you would use a punnet square (ill try my best to show it while typing)
heterozygous means different, so with the purple flower youd get the gene shown as Pp and put it into the punnet square

     P     p
P  PP  Pp
p  Pp   pp

given the possibilities in the punnet square the genes with at least one P is going to be purple and the genes with 2 "p"s are going to be white

so you would have
25% Dominate Homozygous Purple
50% Dominate Heterozygous Purple
25% Recessive Homozygous White
