There are several things that can cause black spots on combs: frostbite, mites, chickens pecking at each other or two different forms of Avian Pox. Google Avian Pox or Fowl Pox to see if that's the trouble--if it is, you just have to wait and see and vaccinate all new chicks/birds.
No, this is not a case of incomplete dominance. In incomplete dominance, a blending of traits would result in an intermediate phenotype. The gray feather color in this case is likely due to a codominant inheritance pattern, where both the black and white alleles are expressed, resulting in a new phenotype.
Offspring are the young of an organism produced either by sexual or asexual reproduction. They share genetic information with their parents, inheriting traits that determine their physical characteristics. Offspring play a crucial role in the continuation of a species and are usually cared for by their parents until they are able to survive on their own.
This principle is known as biogenesis, which states that living organisms are produced from other living organisms. It contrasts with the outdated idea of spontaneous generation, which proposed that living organisms could arise from non-living matter. Biogenesis is supported by modern scientific understanding of genetics and reproduction.
Using selective breeding is exactly how people produced the different dog breeds. They discovered dogs that had the characteristics or skills they wanted and bred them.
Half of the offspring, or 100 rabbits, would be expected to be white when offspring from a heterozygous brown rabbit and a white rabbit are produced. This is due to the dominant-recessive inheritance pattern where brown is dominant and white is recessive.
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!!??!!

This is an example of incomplete dominance.
Incomplete dominance is shown in this scenario, where the offspring have a phenotype that is a blend of the two parent phenotypes. In this case, the heterozygous pink flowering plants are the result of incomplete dominance of the red and white flower alleles.
incomplete dominance
Experiments with four o'clock flowers typically exhibit incomplete dominance, where the heterozygous genotype results in an intermediate phenotype between the two homozygous genotypes.
incomplete dominance
When they don't have pink as their color so the "parents" had to of been either both white or both pink. That is how you can tell when snapdragons are not following the pattern of complete dominance.
Codominance is what it is called. That is when neither allele is completely dominant over the other.
Incomplete dominance: for example is seen in hair type inheritance. Curly hair type (CC) is dominant to straight hair type (cc). An individual who is heterozygous for this trait will have wavy hair (Cc).
the poisoness gas produced by incomplete combustion is carbon monoxide:)
