Question

in ______ dominance, neither allele is completely dominant, resulting in an intermediate phenotype.
______ refers to observable physical traits resulting from the interaction between an organisms genotype and its environment.
______ are the units of heredity that determine specific traits, while alleles are different forms of a gene.
a dominant allele is one that masks the effect of its paired ______.
genotypes are often represented using letters, where dominant alleles are denoted by ______ letters.
sex - linked traits are associated with genes located on the ______ chromosomes.
unlike mendelian traits, polygenic inheritance involves multiple genes contributing to a single ______.

Explanation:

1. In incomplete dominance, neither allele is fully dominant, leading to a blended - intermediate phenotype.
2. Phenotype is the observable physical trait from the genotype - environment interaction.
3. Genes are the units of heredity determining traits.
4. A dominant allele masks the recessive allele.
5. Dominant alleles are denoted by capital letters in genotype representation.
6. Sex - linked traits are on sex chromosomes.
7. Polygenic inheritance has multiple genes contributing to a single trait.

Answer:

1. incomplete
2. Phenotype
3. Genes
4. recessive
5. capital
6. sex
7. trait
