 With the help of a cross, determine how the sex of offspring of a human is identified.

One day students read an article in a newspaper about Thalassemia and were very scared to know the fate of a thalassemia patient. Give a list of the kind of measures they have to use to eradicate this disease from the population.

 Find the probable gametes to be produced from the hybrid plant YyRr produced at F₁ generation in a dihybrid cross experiment.

 Show with the help of cross, who is more important among parents in determining the sex of their offspring?

‘Different genotypes produce the same phenotype’ – Justify the statement in the form a table by taking an example from the result of dihybrid cross of pea plant?

Give your opinion about probable suggestions which can be given to pair of contenders before marriage in order to prevent the spread of a genetic disease from the society already known to you?

Tabulate three pairs of dominant-recessive traits of pea plants as selected by Mendel. State the first law of Mendel as deducted from the experiment of a monohybrid cross.

A colour blind female married a normal male. Judge the probability of colour blindness among their children in the first filial generation. Show with the help of a cross how the first law of Mendel is deviated in the case of Four-O'clock plant in F2 generation.
