The correct answer is both dominant alleles are fully expressed in offspring.
In the incomplete dominance inheritance, one allele is not completely expressed over its paired allele and forms an intermediate trait, whereas in co-dominance, both the alleles express completely resulting into a new phenotype. For example AB blood group in humans.
In the given question Y is the intersection of co-dominance set and incomplete dominance set. Thus, the area Y may have one dominant allele from co-dominance and one allele which is not completely dominant from incomplete dominance.
Therefore, the label to marked area Y may be - both dominant alleles are fully expressed in offspring.
Answer:
C
Explanation:
Incomplete Dominance would mean neither parent has full control.
Answer:
The yellow allele could start to become dominant, or the ones without that allele would die out.
Explanation:
The results are explained if the trait blue eyes is dominant (B) over non-blue (b) and the dominant allele B is lethal in homozygous individuals.
<u>The possible genotypes and phenotypes are:</u>
- Homozygous dominant (BB): lethal
- Heterozygous (Bb): blue eyes
- Homozygous recessive (bb): non-blue eyes
When blue (Bb) is crossed with non-blue (bb) the resulting offspring is 1/2 blue (Bb) and 1/2 non-blue (bb).
When non-blues interbreed (bb X bb) all progeny is non-blue (bb).
