If the mother is a carrier of colour blindness and the father is normal, show the possible genotype and phenotype of the offspring of the next generation, with the help of a punnet square.

If phenotype of father is blood group .O. and genotype of mother is heterozygous .A., what are the possible genotypes and phenotypes of the offspring ?

A colour blind son is born normal parents It shows that

A homozygous tall pea plant with green seeds is crossed with a dwarf pea plant with yellow seeds. (i) What would be the phenotypeand genotype of f_(1) ? (ii) Work out the phenotypic ratio of F_(2) generation with the help of a punnet square.

A homozygous Tall plant (T) bearing red coloured (R) flowers is crossed with a homozygous Dwarf plant (t) bearing white flowers (r):- (1) Give the Genotype and Phenotype of the F_(1) generation. (2) Give the possible combinations of the gametes that can be obtained from the F_(1) hybrid. (3) Give the dihybrid ratio and the phenotype of the offsprings of the F_(2) generation when two plants of the F_(1) generation above are crossed.

If father is normal while mother is carrier of haemophilia

A colour blind boy is born to a couple with a normal colour vision. Write the genotype of the parents.

The sum of genotype and phenotype possible in the Fe generation of test cross if parents are TTRRDDEE and ttrrddee

In a homozygous plant round seeds (R) are dominant over wrinkled seeds (r): Mention the Phenotype and Genotype ratios of the offspring in F_2 generation.
