Explain the chromosomal theory of inheritance.

A true breeding homozygous pea plant with round seeds and yellow cotyledons is crossed with homozygous pea plant with wrinkled seeds and green cotyledons.

Work out the cross to show the phenotype and genotype ratio of F₁ and F₂ generations.

A true breeding homozygous pea plant with round seeds and yellow cotyledons is crossed with homozygous pea plant with wrinkled seeds and green cotyledons.

State the Mendel's generalisation that can be derived from above cross.

Who proposed the chromosome theory of inheritance?

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 round seeded tall pea plant is crossed with round seeded dwarf plant and obtained progeny are with following phenotypes
$3$ - Tall, Round
$3$ - Dwarf, Round
$1$ - Tall, Wrinkled
$1$ - Dwarf, Wrinkled
