The genotype of a plant showing the dominant phenotype can be determined by

(1) test cross

(2) dihybrid cross

(3) pedigree analysis

(4) back cross

A common test to find the genotype or hybrid is by :

(1) crossing of one F₂ progeny with male parent

(2) crossing of one F₂ progeny with female parent

(3) studying the sexual behaviour of F₁ progenies

(4) crossing of one F₁ progeny with recessive parent

Test cross involves :

(1) crossing between two geneotypes with recessive trait

(2) crossing between two F₁ hybrids

(3) crossing the F₁ hybrid with a double recessive genotype

(4) crossing between two genotypes with dominant trait

Mating of an organism to a double recessive in order to determine whether it is homozygous or heterozygous for a character under consideration is called

(1) reciprocal cross

(2) test cross

(3) dihybrid cross

(4) back cross

In a pea plants, green pod colour is dominant over yellow pods. 1000 seeds taken from a pea plant on germination produces 760 green pod and 240 yellow pod plants. The parental genotype and phenotype of the seed plant are 

(1) Heterozygous and yellow

(2) heterozygous and green

(3) homozygous and yellow

(4) homozygous and green
