In a cross between yellow round $(YYRR)$ and pure breeding pea plants having green wrinkled $(yyrr)$ seeds,find out the total number of seeds (plants) having yellow colour in the $F_2$ generation out of $16$ offspring.

$A$ human male produces four types of gametes $AB, Ab, aB,$ and $ab$ in equal proportions. What is the corresponding genotype of this individual?

In peas,tallness is dominant over dwarfness and red colour of flowers is dominant over the white colour. When a tall plant bearing red flowers was pollinated with a dwarf plant bearing white flowers,the different phenotypic groups were obtained in the progeny in numbers mentioned against them:
Tall,Red $= 138$
Tall,White $= 132$
Dwarf,Red $= 136$
Dwarf,White $= 128$
Mention the genotypes of the two parents and of the four offspring types.

Which traits did Mendel consider for his dihybrid cross experiment?

In the $F_{2}$ generation of a Mendelian dihybrid cross $(TTRR \times ttrr)$,which of the following statements is correct?

In Mendel's dihybrid cross,what is the proportion of the dominant homozygous plants in the $F_2$ generation (in $/16$)?
