An independent variable is the variable that is changed. A dependant variable is the variable that is measured. And the control refers to all the other variables that need to be controlled in the experiment.
For example, if you were to conduct an experiment to see how quickly different amounts of water boiled; the independent variable would be the amount of water, the dependant variable would be the time it took to bail and the controlled variables would be the type of water, the temperature and type of heat source, etc.
Don’t worry this is pretty easy :)
The answer is -
50% recessive alleles
50% dominate alleles
explication- find out what alleles you’re working with (heterogeneous and homogeneous)
[heterogeneous is 1 dominant and 1 recessive- homogeneous is 2 of the same alleles they can be dominant or recessive]
We’re working with a parent with heterogeneous and another parent with recessive homogeneous.
draw a allele chart

|_|_|
|_|_|
they look like this and take your first parents alleles and put them at the top
L s
_ _
|_|_|
|_|_|
it should look like this, then take your parent with both recessive and put them vertical to the box
L s
_ _
s |_|_|
s |_|_|
it should look like this, now you drag one letter down and one letter across for each box
L s
__ __
s|Ls|ss |
s|Ls|ss |

it’s should look like this when they’re done, i think you’re doing a grade below me in biology so the ratio should be 50/50 for both phenotype and genotype.
TRY TO LEARN THE VOCABULARY IT HELPS A LOT AND BASICALLY TELLS YOU THE ANSWERS!
GOOD LUCK :)
Iceberg Lettuce. It is a really crispy cabbage looking lettuce. It can be dark green or red.
