Which of these is an example of a PHENOTYPE? A-an allele for yellow flower color within a flower's genome
B-yellow flower color
C-a gene that tells how big someone's nose will be
D-two identical alleles for nose size

I think this is B: Yellow Flower Color

I think phenotypes focus on the physical characteristics rather than the alleles and genes (genotypes).

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.
