    Heterozygous
  3. C
    Phenotype
  4. D
    Hemizygous

Answer

Homozygous
Homozygous is the genetic term for an organism carrying two identical alleles for a given gene locus.

Step-by-Step Solution

1
Define genetic zygosity terms.
Alleles are alternative forms of a gene located at the same locus on homologous chromosomes.
Comparing maternal and paternal alleles determines the zygosity of the gene locus.
2
Identify the term for matching alleles.
When an individual inherits identical alleles from both parents for a gene, the genetic condition is homozygous.
The prefix 'homo-' means same, indicating identical alleles.
