Verified step by step guidance

Understand the concept of dominant-recessive inheritance: In this type of inheritance, one allele is dominant over the other, which is recessive. The dominant allele will mask the expression of the recessive allele in a heterozygous individual.

Define heterozygous: A heterozygous individual has two different alleles for a particular gene, one inherited from each parent. In this case, one allele is dominant, and the other is recessive.

Identify the phenotype expression: In a heterozygous individual, the dominant allele's trait will be expressed in the phenotype, while the recessive allele's trait will not be visible.

Consider the options given: The options provided are 'segregated', 'autosomal', 'recessive', and 'dominant'.

Select the correct phenotype expression: Based on the understanding of dominant-recessive inheritance, the phenotype expressed in a heterozygous individual will be 'dominant'.
