Transformation during Sexual Reproduction

A homozygous tall pea plant with yellow seeds is crossed with a dwarf pea plant with green seeds. The phenotypic ratio of its F₂ plants would be:

The percentage of double dominant phenotypic progeny formed in F₂ generation of Mendel's dihybrid cross is:

How many Pea plants will be dwarf in a mendelian dihybrid cross for height and flower color in F₂ generation ?

In 'Mendel' dihybrid cross, which of the following result was obtained in ${\mathrm{F}}_2$ generation?

In colour blindness red, green and other colours appear as

Amylase enzyme acts on the starch.

The genetic identity of the human male is determined by

Which of the following reproduction creates the greatest diversity?

Seed traits of a given plant species following genetic inheritance are:

$S=$ long, $s=$ short;
$W=$ wrinkled, $w=$ smooth;
$Y=$ yellow, $y=$ white;
$R=$ ribbed, $r=$ grooved
A cross was performed between two plants, $P$ and $Q$ of the same species; wherein, the plant $P$ bears seeds that are homozygous recessive for grooved, homozygous dominant for long trait, and heterozygous for wrinkled texture and yellow colour. The plant $Q$ bears seeds that are homozygous recessive for short and smooth traits, homozygous dominant for yellow colour and ribbed trait. Given that there are no influencing factors, state the resulting phenotype of the offspring for this cross.

A cross between two plants with genotypes, $PpQq$ and $PpQq$ was carried out where $P$ and $Q$ are dominant over $p$ and $q$, respectively. Of the total progeny obtained, the proportion of the offspring that would only express one of the two dominant alleles is

Two laws of inheritance proposed by Mendel are

A cross wạs carried out between two individuals, heterozygous for two pairs of genes. Assuming segregation and independent assortment, the number of different genotypes and phenotypes obtained respectively would be

A pea plant with yellow and round seeds crossed with another pea plant with green and wrinkled seeds produced $51$ yellow round seeds and $49$ yellow wrinkled seeds. Genotype of plant with yellow and round seeds must be _____.

The Law of independent assortment was proved by

"When two pairs of traits are combined in a hybrid, segregation of one pair of characters is independent of the other pair of characters".

Which of Mendel's laws/principles explains the above statement?

When a heterozygous pea plant with yellow round seeds is crossed with a homozygous pea plant with yellow round seeds, the genotype not obtained is

If linkage was known at the time of Mendel then which of the following laws, he would NOT have been able to explain?

What will be the probability of genotype $\mathrm{TTrr}$in ${\mathrm{F}}_2$ generation of a typical Mendelian dihybrid cross?
