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.
A dihybrid condition is ______.
In a dihybrid cross AABB x aabb, F2 progeny of AABB, AABb, AaBB and AaBb occurs in the ratio of ______.
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.
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.
