5. Explain: In dominant/recessive inheritance patterns, the dominant allele is always expressed when present. The recessive allele is only expressed when the dominant allele is not present. Use your observations from this activity to describe how codominant inheritance patterns differ from dominant/recessive inheritance patterns.

What is the genotype for black chickens ____?
Expert-Verified Answer The genotype for a black chicken is BB. EXPLANATION : The colour black in a chicken is expressed by the allele B. The color white allele is expressed as W similarly.
What is the genotype for black chickens for white chickens for Erminette chickens?
In some chickens, the gene for feather color is controlled by codominance. The allele for black feathers is B and white feathers is W. The heterogenous genotype is known as erminette.
What is the phenotype of genotype AA?
A phenotype consists of only those traits or antigens that can be directly typed, whereas a genotype is the sum of all genes a person has inherited within a blood group system....Table 4-5. Correlation of ABO phenotypes and genotypes. PhenotypePossible GenotypeAAA or AOBBB or BOABABOOO
What color is a heterozygous chicken?
In chickens, black and white feathers are codominant. Heterozygous chickens have a checkered pattern. A checkered hen is crossed with a checkered rooster.
How is the inheritance pattern shown by this flower different from other inheritance patterns you have seen or studied gizmo?
How is the inheritance pattern shown by this flower different from other inheritance patterns you have seen or studied? The dominant allele is not completely expressed like it normally is. This flower has codominance instead of having one allele that is completely dominant over the other.
Are black feathers codominant in chickens?
For Example: In chickens, the allele for black feathers is co-dominant with the allele for white feathers. These chickens will have BOTH black and white feathers.
What is codominance and chicken genetics?
Codominance, is a situation in which both alleles are equally stong and both alleles are visible in the hybrid genotype. An example of codominance is found in chickens. When white chickens are crossed with black chickens, the result is not a grey chicken, but a chicken with both black and white feathers.
What is the genotype for white chickens *?
If the "feather color allele" on both chromosomes carries the gene for white feathers (n), the chicken will have the genotype (n,n) and will be phenotypically white.
