1) genotype of the homozygous dominant plant is DDWW and genotype of the homozygous recessive plant is ddww.

DDWW * ddww

DW | DW | DW | DW | |

dw | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) |

dw | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) |

dw | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) |

dw | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) | DdWw ( tall plant with purple flowers) |

2) a) here all the progenies are tall plants with purple flowers

so probability of getting tall plants with purple flowers= number of tall plants with purple flowers/total number=16/16=1

possible genotypes= DdWw

b) probability of producing dwarf plant with white flowers= number of the dwarf plant with white flowers/total number=0/16=0

the possible genotypes of dwarf plant with white flowers = ddww

c) probability of getting tall plants with white flowers= number of tall plants with white flowers/total number of plants=0/16

the possible genotypes of tall plants with white flowers is DDww, Ddww

d) probability of producing dwarf plant with purple flowers= number of the dwarf plant with purple flowers/total number=0/16=0

possible genotypes of dwarf plant with purple flowers are ddWW, ddWw.
