From a mating of two dihybrid individuals $(AaBb \times AaBb)$,how many of the $16$ possible zygote combinations would be expected to be homozygous dominant for both genes?

Mrs. Verma has a pair of autosomal genes '$Bb$' and she also carries an $X$-linked gene '$dd$'. What will be the percentage of gametes that contain the genes '$bd$'?

How many different types of gametes will be formed by a pea plant with genotype $TtYy$?

$A$ heterozygous trihybrid plant produces .....

In a dihybrid cross,what is the proportion of $RrYy$ offspring obtained from the selfing of an $RrYy$ plant (in $/16$)?

In a plant,gene '$A$' is responsible for tallness and '$a$' is the recessive allele for dwarfness. Gene '$B$' is responsible for red flower color and '$b$' is the recessive allele for white flower color. $A$ plant with genotype $AaBb$ (tall and red) is crossed with a plant with genotype $aaBb$ (dwarf and red). What is the percentage of dwarf-white flowered plants in the progeny (in $\%$)?
