If an individual has two identical alleles for a trait, they are said to be:

Homozygous means having two of the same alleles, like two matching socks. If the alleles are different, it?s called heterozygous, like wearing one red sock and one blue sock.
The observable traits of an organism are called: In humans, how many chromosomes are there in a typical somatic cell? Which structure holds the genetic code and is found in the nucleus of eukaryotic cells? What is the purpose of a Punnett square in genetics? If a mutation occurs in a somatic cell, what is the consequence for the offspring? What term describes a change in the sequence of DNA? What is the role of tRNA in translation? In pea plants, tall (T) is dominant over short (t). If a homozygous tall plant (TT) is crossed with a short plant (tt), what will the offspring be? If an individual has two identical alleles for a trait, they are said to be: Which of the following best explains why siblings can look different from each other? The fundamental unit of heredity is called a: What is the name of the process where DNA makes a copy of itself? What process separates alleles during gamete formation? What is the role of ribosomes in the cell? Which type of RNA carries the genetic information from DNA to the ribosome? What is the result of a cross between two heterozygous individuals (Rr x Rr) for a simple Mendelian trait? Which nitrogenous base is not found in RNA? In genetic terms, what is a recessive allele? Which of the following describes a genotype? What kind of inheritance pattern is displayed when both alleles are equally expressed in a heterozygous organism?
