Anne mentions that her cousin has a congenital anomaly. You would know that this is sometimes also referred to as: Select one: a. an autosomal disorder b. a birth defect c. a sex-linked trait d. a heterozygous trait

## Step 1<br />The problem is asking for the term that is sometimes used to refer to a congenital anomaly. A congenital anomaly is a condition that is present at birth and can be physical or functional. <br /><br />## Step 2<br />Let's analyze each option:<br />- An autosomal disorder is a type of genetic disorder that is caused by mutations in genes on the autosomes (chromosomes 1-22). While some congenital anomalies can be autosomal disorders, not all of them are.<br />- A birth defect is a broad term that includes any physical or functional abnormality present at birth, which can be due to genetic, environmental, or unknown causes. This term is synonymous with congenital anomaly.<br />- A sex-linked trait is a trait that is determined by genes located on the sex chromosomes (X and Y). While some congenital anomalies can be sex-linked, not all of them are.<br />- A heterozygous trait refers to having two different alleles for a particular gene. This term does not specifically refer to congenital anomalies.<br /><br />## Step 3<br />Based on the above analysis, the term that is sometimes used to refer to a congenital anomaly is "a birth defect".
