Alternate forms of a trait are called:Group of answer choicesalleleslocustrisomiesgenesamino acids

Step 1: Break Down the Problem

We need to identify the correct term that refers to alternate forms of a trait. The options provided include alleles, locus, trisomies, genes, and amino acids.

Step 2: Relevant Concepts

1. Alleles: Different versions of a gene that determine specific traits.
2. Locus: The specific location of a gene on a chromosome.
3. Trisomies: A condition where there are three copies of a chromosome instead of the usual two.
4. Genes: Basic units of heredity that are made up of DNA and influence traits.
5. Amino Acids: The building blocks of proteins, not directly related to traits.

Step 3: Analysis and Detail

Among the options, "alleles" specifically refer to the different variations of a gene that can manifest in varying traits. For example, the gene for flower color in peas can have an allele for purple flowers and another for white flowers.

Step 4: Verify and Summarize

The term that best fits the definition of alternate forms of a trait is "alleles." This is because alleles account for the variations seen in specific characteristics.

Final Answer

Alleles are the alternate forms of a trait.
