In a cross performed between parents considering two contrasting characters yellow round and green wrinkled seeds. In the $F_2$ generation progeny,the ratio of yellow and green will be . . . . . . .

In plants,red color $(R)$ is dominant over yellow $(r)$ and tallness $(T)$ is dominant over dwarfness $(t)$. If a plant with genotype $RRTt$ is crossed with a plant with genotype $rrtt$,what will be the result?

How many different types of gametes can be formed by $F_1$ progeny,resulting from the following cross: $AA BB CC \times aa bb cc$?

In pea plants,red flowers $(R)$ are dominant over white flowers $(r)$ and tall plants $(T)$ are dominant over dwarf plants $(t)$. The table below shows the gametes and the possible offspring produced in a dihybrid cross. The numbers $1$ to $16$ represent the genotypes of each individual cross $(e.g., 3 = RrTT)$.

	$RT$	$Rt$	$rT$	$rt$
$RT$	$1$	$2$	$3$	$4$
$Rt$	$5$	$6$	$7$	$8$
$rT$	$9$	$10$	$11$	$12$
$rt$	$13$	$14$	$15$	$16$

If plant $7$ is crossed with plant $12$,then what proportion of the offspring produced will be homozygous for both the recessive characters (in $\%$)?

If the genotype of an organism for two pairs of genes is represented by $AaBb$,then the possible genetic combinations of gametes after meiosis will be:

Heterozygous round and yellow seeded pea plants were selfed and a total of $800$ seeds were collected. What is the total number of seeds with the first dominant trait (round) and the second recessive trait (green)?
