It is phenotype becoz smoothness is outer character
Answer:
1st question is the rinsing hands for 20 sec with soap bc it has the less amount of substance left on it.
2nd question is to get more effective results
3rd is human error, and make sure to pay attention bc that messes up your results
Explanation:
hope this helps
Answer:
See the answer below
Explanation:
a) Since the pink phenotype is heterozygous, the genotype would be RW.
b) The pink genotype is RW. Hence, a cross between two pink snapdragons will go thus:
RW x RW
RR RW RW WW
<u>Expected genotypes:</u> 1/4 RR, 1/2 RW, 1/4 WW
<u>Expected phenotypes:</u> 1/4 red-flowered plants, 1/2 pink-flowered plant, 1/4 white-flowered plant.
Limits to variation The most obvious limit to natural selection is that suitable variation may not be available. This may be because certain phenotypes cannot be built, being ruled out either by physical law or by the properties of biological materials.
