The production of gametes by the parents, formation of zygotes, the F1 and F2 plants, can be understood from a diagram called:
1. Punnett square
2. Net square
3. Bullet square
4. Punch square
A true-breeding plant is:
1. | one that is able to breed on its own |
2. | produced due to cross-pollination among unrelated plants |
3. | near homozygous and produces offspring of its own kind |
4. | always homozygous recessive in its genetic constitution |
Alleles are:
1. different phenotype
2. true breeding homozygotes
3. different molecular forms of a gene
4. heterozygotes
F2 generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as 1: 2: 1. It represents a case of:
1. Co-dominance
2. Dihybrid crosses
3. Monohybrid crosses with complete dominance
4. Monohybrid crosses with incomplete dominance
