Inheritance of One Gene
Inheritance of One Gene: Overview
This topic covers concepts such as First Filial Generation, Second Filial Generation, Monohybrid Cross, Law of Dominance, Law of Segregation, and Punnett Square.
Important Questions on Inheritance of One Gene
Look at the given diagram and answer the following question :
Identify the phenotypic ratio of A, B, C, D.
Look at the diagram given below and answer the following question :
Identify the genotypes of A, B, C, D.
You are given tall pea plants with yellow seeds whose genotypes are unknown. It was crossed with a dwarf pea plant with green seeds. The progeny obtained has equal ratio of tall and dwarf plants and equal proportion of green and yellow seeds. The genotype of the first plant is:
When a violet flower producing plant was crossed with white flower producing plant, the progeny obtained had all violet flower.
The genotype of first parent was homozygous or heterozygous:
If a homozygous tall plant is crossed with homozygous dwarf plant, the offspring will be
If a homozygous red flowered plant is crossed with a homozygous white flowered plant, the off springs would be
The characteristic features of a plant with are:
i) It is a heterozygote that resulted from a dihybrid cross
ii) It represents the genotype
iii) The hybrids contain alleles which express contrasting traits
iv) The two alleles are derived from the same parent
The correct combination is:
Identify the correct expression of the F1 generation of monohybrid ratio.
Which among the following is not possible w.r.t law of purity of gametes?
When Mendel crossed plants with a pair of contrasting characters, he derived the

Ratio of offspring from Tt x tt cross is
If the genotype of male plant is AA and female plant is aa, what will be the genotype of endosperm and embryo respectively?
''Gametes are never hybrid'', which of the following law states this concept?
Statement-1 : Law of segregation is true for monohybrid crosses.
Statement-2 : In dihybrid cross, two alleles for a character can be present in a single gamete.
When heterozygous tall plants are self-pollinated, then tall and dwarf plants are obtained. This explains
In mice, black coat colour (allele ) is dominant to brown coat colour (allele ). The offspring of a cross between a black mouse and a brown mouse were allowed to interbreed. What percentage of the progeny would have black coats?
From a single ear of corn, a farmer planted 200 kernels which produced 146 tall and 44 short plants. The genotypes of these offsprings are most likely
