The guidelines for making good and accurate observations are:

1. Standardise the experimental setup: Know the precision and the accuracy of the instrument used to make observations. Example, thermometer with a least count of 1°C cannot measure in fractional values.

2.Take careful measurements: Holding the instrument properly without causing any disturbance is the key.

In watermelons, solid green rind color (G) is dominant to stripes (g).
stiks02 [169]

There are chances of 75% solid green coloured rind in watermelons.

Explanation:

Dominant trait = Solid Green rind G

Recessive trait= stripes g

Given that both the parent plants are heterozygous so their alleles will be

Gg Gg

From the Punnet square

          G        g

G      GG     Gg

g       Gg     gg

The phenotype ratio is 3:1  ( 3 watermelons with the green colour rind and 1 with striped rind observed)

Genotype ratio is 1:2:1

From the observation, we can say that 75% of the watermelons will have solid green colour rind because G is dominant over g.
