What is the difference of complete dominance and incomplete dominance?
Complete Dominance: Where in the dominant gene completely masks the effect of the resesive gen in heterozygous conditions. Ex. Tt or Rr. Incomplete Dominance: When 2 or more alleles influence a phenotype. Ex. Flowers. Codominance: When both alleles for a gene are expressed in heterozygous offspring. Ex. Bloodtype.
What type dominance do pea plants show?
The recessiive trait one is 50%,dominant is 75% or above.
How do incomplete dominance and codominance improve the quality of plant and animal breeds?
During incomplete dominance both the allelic genes in a chromosome in dominant condition inherit a character in the off-springs. When only one gene out of the allelic pair is dominant and its counterpart is recessive, we get incomplete expression. For example a pea plant with red flowers is crossed with another plant having white flowers, the f1 plants are pink flowered. On selfing of f1 plants we get f2 progeny in the ratio of 1 red: 2 pink : 1 white flowered plants. These pink flowered plants show incomplete dominance.
What is incomplete dominace?
Incomplete dominance is where 2 dominant traits are combined, but neither show up in the offspring. This term is easily confused with co-dominance, but there is a difference. An example of incomplete dominance would be where a white flowering plant pollinates a red flowering plant, but their offspring are all pink flowering plants. Since both white and red were dominant, they canceled each other out, and the median color pink shows up in the next generation. Co-dominance is where 2 dominant traits are BOTH expressed. This would be the case if a white flowering plant pollinates a red flowering plant, and their offspring have flowers that are speckled with red and white dots. Both colors still show up, but neither one completely dominates the other.
Plants release these into their surroundings to produce offspring?
No plants release oxygen
What type of dominance do pew plants show?

How does snapdragons grow?
Actually, snapdragons aren't necessarily outdoor plants. They can grow either indoors or outdoors... Snapdragons grow just like any other flower.
What dominance is a sweet pea tendrils?
When sweet pea plants with tendrils are crossed with those without tendrils, all the offspring have tendrils. This is simple dominance with tendrils dominant and no tendrils recessive.
How do snapdragons attract bumblebees?
Snapdragons attract bumblebees by olfactory signals (scent). It is also known that bumblebees are attracted to certain colors of plants
Why pink snapdragons were produced instead of red snapdragons?
I am assuming you are talking about the breeding of a plant with white flowers and a plant with red flowers. The reason the new plants will have pink flowers is because the flower color in snapdragons is an example of INCOMPLETE dominance. Red is the stronger allele, but not completely... so the white it not completely overpowered. So the new trait of the new plant is somewhere in between the parent phenotypes: Red mixed with white- or pink! did you know they actually snap!!??!!
What are antirrhinums?
Antirrhinums are biennial plants grown for their flowers. They are commonly called snapdragons.
What is the scientific name of a snapdragon?
The scientific name of a snapdragon is Antirrhinum majus.

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 diseases are snap dragons prone to and how do you prevent them?
Snapdragons or Antirrhinum are prone to rust. This is why although they are perennial plants they are usually grown as annuals.
