True or False
21.A pure line is not always a true breeding line
22.A dihybrid upon selfing is expected to produce 9 different
genotypes
23.A 9:3:3:1 phenotype ratio is obtained in the f2 assuming
complete dominance and independent assortment of genes by
selfing a monohybrid
24.All perfect flowers are complete flowers but not all
complete
flowers are perfect
25.The embryonic sac contains six nuclei
26.A complete flower is always bisexual flower
27.Among vascular plants, the gametophytic generation
dominates the sporophytic generation
28.Maize is a monoecious plant
29.Both self-incompatibility and cleistogamy enforce self-
fertilization
30.In monohybrid inheritance, when two heterozygous are
mated,
a minimum of four individuals required for all classes to be
represented in their correct proportion.
31.Double fertilization leads in the formation of a triploid
endosperm and a diploid zygote
32.When a homozygous dominant and a heterozygous recessive
of a single gene pair are mated, all the offspring will be
heterozygous for the gene
