Select the correct statement from the ones given below with respect to dihydrid cross
In a dihybrid cross, F2 phenotypic ratio is 13 : 3. It is case 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.
How is the sex of a newborn determined in humans?
Do genetic combination of mothers play a significant role in determining the sex of a new born?
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.
What will be set of genes present in the F1 generation?
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.
When two hybrids rrTt and Rrtt are gassed, the phenotype ratio of offspring should be:
