State Mendel’s law of Independent Assortment.
Under which conditions does the law of independent assortment hold good and why?
Test cross involves
In pea plants, yellow seeds are dominant to green. If a heterozygous yellow seed pant is crossed with a green seeded plant, what ratio of yellow and green seeded plants would you expect in the F1 generation?
Select the correct statement from the ones given below with respect to dihydrid cross
In a test cross involving F1 dihybrid flies, more parental type offspring were produced than the recombination type offspring. This indicates
Among the following characters which one was not considered by Mendel in his experimentation pea?
Explain the law of dominance in a monohybrid cross.
Findings of Gregor Mendel were rediscovered by the following scientists EXCEPT for ______
A normal green male maize is crossed with albino female. The progeny is albino because ______.
Mendel’s Law of independent assortment holds good for genes situated on the ______.
Two genes ‘A’ and ‘B’ are linked. In a dihybrid cross involving these two genes, the F1 heterozygote is crossed with homozygous recessive parental type (aa bb). What would be the ratio of offspring in the next generation?
Assertion: When the two genes in a dihybrid cross are situated on the same chromosome, the proportion of parental gene combinations is much higher than the nonparental type.
Reason: Higher parental gene combinations can be attributed to crossing over between two genes.
Sahil performed an experiment to study the inheritance pattern of genes. He crossed tall pea plants (TT) with short pea plants (tt) and obtained all tall plants in F1 generation.
When F1 plants were self-pollinated, a total of 800 plants were produced. How many of these would be tall, medium height or short plants? Give the genotype of F2 generation.
When two hybrids rrTt and Rrtt are gassed, the phenotype ratio of offspring should be:
