Because all Purple flower plants are dominant and express the color purple. This can be seen in a homozygous cross, or a heterozygous cross, ( shown above ) White plants, to breed true, must be in homozygous condition.

Why were all the offsprins purple when gregor menel crossed true breeding purple flowered plants with true breeding white flowered plants?

All the offspring were purple because Mendel was dealing with simple genetic dominance. The purple true breeding parent was homozygous dominant and the true breeding white parent was homozygous recessive. When those two are crossed they create only heterozygous offspring (look up a punnett) and since this is simple dominance those heterozygous will show the phenotype of the dominant allele which is purple.


What does codominonce mean in geneticists?

Codominance is a condition where heterozyous alleles at the same site produce and intermediate result. Ex. Red flowered plant crossed with White flowered plant yields 100% Pink flowered offspring. Ex. White Shorthorn cow crossed with Red Shorthorn yields 100% roan offspring.


Suppose two white flowered pea plants are crossed and produce 1000 offspring how many of those offspring would you expect to have white flowers?

because it helped Mendel discover which plants would be crossed to produce offspring.
