What did mendel predict was the probability of producing a tall plant from a genetic cross of two hybrid tall.

Question

plants?

four in four

three in four

two in four

or

one in four

please....

Answer 1

in heterozygous condition the genotype of pea plant is Tt*Tt

when crossing takes place one homozygous tall and two heterozygous tall and one homozygous dwarf are obtained

                so 3 out of 4 are tall phenotypically and only one tall homozygous plant genetically.the genetic make up is called genotype.the physical appearance is called phenotype

Answer 2

T = tall

S = small  assuming the short gene is recessive

The two parent plants would be TTXTT, TTXTS or TSXTS

TTXTT = 4/4 Tall

TTXTS =4/4 tall though some offspring would carry short gene that would not be noticable until they reproduced.

This one is the HYBRID

TSXTS= TT,TS,TS,SS = 3/4 tall, 1/4 short

Answer 3

Tt x Tt

    T    t

T TT Tt

t  Tt   tt

1 homozygous tall plant and 2 heterozygous tall plants

3 in 4
