Question

Explain Mendelis observation when
be boossed a homo Zygous tullut plant
with homozygous decouf (tto plant
followed by sely cross​

Answer 1

${\tt{\red{\underline{\underline{\huge{Answer:}}}}}}$

Crossing a homozygous tall (TT) plant with plant homozygous dwarf (tt) plant gives heterozygous tall (Tt) plants in F1 progeny. Here, tallness was dominant over dwarfism and only tall plants were obtained in F. Self-pollination of two F1 plants gave F2 generation.

Answer 2

Answer:

Monohybrid cross

at f1 generation

all the plants were tall

and in f2 generation 3 were tall and 1 was dwarf

dihybrid cross

at f1 all were tall

at f2 it was in ratio 9:3:3:1
