Explanation:

Because this is necessary for the data to be valid. If you are testing one variable but the conditions of the control and experimental are different besides that variable, you will have more than one variable and will not be able to tell if the results of the experiment are caused by the variable you were trying to test.

(Sorry for repeating the word variable so much, lol)

In a mono hybrid cross of heterozygous pea plant with round (R) yellow (Y) seeds there will be genotype ratio of 9 _____ 3,____
andreev551 [17]

Genotype ratio refers to the probability of each type of thing (in this case, round/yellow seeds) occurring based on the Punnett square. If you were to write out how many of each specific hybrid occurred in the square, you'd get:

1 RRYY

2 RRYy

2 RrYY

4 RrYy

1 RRyy

1 rrYY

1 rryy

What does this tell us? In this case, the only thing that matters is the capital letter (since that's the dominant trait and will determine whether the seed is/isn't round/yellow).

Looking at each one, you see some of them are the same - for example, RRYY and RRYy both end up as round and yellow. RrYy is too, as is RrYY.

So, you end up with 9 round and yellow; 3 round and not yellow; 3 not round and yellow; 1 not round and not yellow.
