Monohybrid Cross Further Understanding

Test cross involves:

1.	crossing between two genotypes 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 the trait

A common test to find the genotype of a hybrid is by:

1. crossing of one F₂ progeny with a male parent

2. crossing of one F₂ progeny with a female parent

3. studying the sexual behaviour of F₁ progenies

4. crossing of one F₁ progeny with a male parent

In pea plants, yellow seeds are dominant to green. If a heterozygous yellow-seeded plant is crossed with a green-seeded plant, what ratio of yellow and green-seeded plants would you expect in F1generation?

1. 50:50

2. 9:1

3. 1:3

4. 3:1

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

In a plant, black seed color (BB/Bb) is dominant over white seed color (bb). In order to find out the genotype of black seed plant, with which of the following genotype will you cross it?

1.	bb	2.	Bb
3.	BB/Bb	4.	BB
