Directions: Type your answer in the box. Many organisms have two sets of chromosomes and are diploid. Goldfish have four sets of chromosomes and are considered tetraploid. If a goldfish has a haploid number of 25 chromosomes how many total chromosomes will it have? square chromosomes

## Step 1<br />The problem provides us with the information that goldfish are tetraploid, which means they have four sets of chromosomes. <br /><br />## Step 2<br />The problem also provides us with the information that the haploid number of chromosomes in goldfish is 25. The haploid number is the number of chromosomes in a gamete of an organism, which is half the number of chromosomes in a somatic cell.<br /><br />## Step 3<br />To find the total number of chromosomes in a goldfish, we need to multiply the haploid number by the number of sets of chromosomes. <br /><br />### **Total number of chromosomes = Haploid number * Number of sets of chromosomes**<br /><br />## Step 4<br />Substitute the given values into the formula:<br /><br />### **Total number of chromosomes = 25 * 4**
