Terminologies Used in Genetics

Which one of the following genotypes can form only 2 different types of gametes?

The below diagram represents

The recessive character of Mendel was

If after a cross, a particular plant produces $50\%$ dominant characters and $50\%$ recessive characters, the probable genotypes of the parents would be

A heterozygous tall plant which produces round seed $\left(\mathrm{RR}\right)$ is crossed with a homozygous dwarf plant which produces wrinkled seeds. The offspring would be in the phenotypic ratio:

In a plant, red flower $\left(\mathrm{R}\right)$ is dominant over yellow flower $\left(\mathrm{r}\right)$ and tallness $\left(\mathrm{T}\right)$ dominant over shortness $\left(\mathrm{t}\right)$. A plant with $\mathrm{RRTt}$ genotype is crossed with plant of $\mathrm{rrtt}$ genotype. The progeny is:

How would you test a pea plant whether it is pure or hybrid for tallness?

From the given statements, find the correct option:

I. Test crosses are used to determine the unknown genotype of an organism within one breeding generation.

II. Test cross is a cross between F₁ hybrid and dominant or recessive parents.

An allele that mask the effect of another allele is called

Genetically identical progeny is produced when an individual :

How many different kinds of gametes will be produced by a plant having the genotype $\mathrm{AABbCC}?$
 

In an organism, tall phenotype is dominant over recessive dwarf phenotype and the alleles are designated as $T$ and $t,$ respectively. Upon crossing two different individuals, total $250$ offsprings were obtained, out of which $124$ displayed tall phenotype and rest were dwarf. Thus, the genotype of the parents were

The hereditary characters are due to

Find out the statements that come under the scope of genetics from the following.

'One gene one enzyme' concept was put forward by:

The term "genotype" was coined by

Who coined the term "gene"?

If a cross made between two individuals produces offspring with $50\%$ dominant character $\left(\mathrm{A}\right)$ and $50\%$ recessive character (a), then the genotypes of the parents are
