The ratio of offspring on F2 generation in a dihybrid cross.
Multiple Choice Question
When two individuals differing in at least one character are crossed, the process is known as:
The physical expression of a gene is called ______.
Under which conditions does the law of independent assortment hold good and why?
In a test cross involving F1 dihybrid flies, more parental type offspring were produced than the recombination type offspring. This indicates
Identify the statementls that is/are NOT the correct reason/s for Mendel's success in his hybridization experiments.
i. Each factor controlled the single trait and is located on separate chromosomes.
ii. In the pea plant, contrasting characters can be easily recognized.
iii. Mendel carefully recorded the number of plants of each type and expressed his results as ratios.
iv. Mendel performed biochemical assays for identifying the position of 'factors' on chromosome.
In a dihybrid cross, if you get 9:3:3:1 ratio it denotes that ______.
A fruit fly exhibiting both male and female traits is ______.
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.
What is the difference between genetic drift and change due to natural selection?
According to the evolutionary theory, formation of a new species is generally due to
From the list given below, select the character which can be acquired but not inherited
Two pea plants - one with round yellow seeds (RRYY) and another with wrinkled green (rryy) seeds produce F1 progeny that have round, yellow (RrYy) seeds.
When F1 plants are self-pollinated, which new combination of characters is expected in F2 progeny? How many seeds with these new combinations of characters will be produced when a total 160 seeds are produced in F2 generation? Explain with reason.
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.
Give a reason why only tall plants are observed in F1 progeny.
Independent assortment means:
In the Mendelian dihybrid cross when heterozygous round yellow is self grossed, round green offsprings are represented by the genotype.
The Law of independent assortment is applicable for the traits which ______
