A phenotype is the composite of an organism's observable traits. The answer to the question, the cross that will yield four phenotypes in the 1:1:1:1 ratio is fifty.
if you mean in terms of what their offspring will be? then you need to do a monohyrid cross, the gametes being RW and WW sooo x R W W RW WW W RW WW it will be 1:1 ratio of pink to white offspring
Dihybrid cross
3:1 ratio Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio
The genotypic ratio of a cross of Aa and Aa is: one AA, one aa, and two Aa. Or 1:2:1
dihybrid cross
that the parents were true-breeding for contrasting traits. NOT TRUE. If so, all the offspring would be identical genotypes. Think of a classic cross that gives you a 3:1 ratio and write it out. It would suggest that the parents were both heterozygous for a single trait.
What is the ratio of heterozygous offspring to total offspring in the punnett square
3:1
9:3:3:1 is the phenotypic ratio of the offspring.
That the parents were both heterozygous!
If the parents were AA and AA for example then the phenotype ratio will be 1 A (the dominant allele). The genotype will be 1Aa.
The offspring will look more like the mom but they will have mid hair.
