By changing the controlled variable.
Answer:
Yellow seed colour (heterozygous)
Explanation:
Since we are performing experiment on the garden pea, so in the garden pea Yellow seed color is dominant and green one is recessive.
The allele responsible for the seed colour is denoted by Y.
So,
Homozygous parent having Yellow seeds will have allelic configuration as YY and the other homozygous parent with green seeds will have yy as pair of alleles.
In the cross of YY × yy the F1 progeny will be Yy which means F1 offspring will will be heterozygous and have Yellow seed colour because Yellow seed colour is dominant over the green colour. Green colour will express itself only in the homozygous condition.
