Which of the following statements regarding genotypes and phenotypes is false? Alleles are alternate forms of a gene. The expressed physical traits of an organism are called its phenotype. The genetic makeup of an organism constitutes its genotype. An organism with two different alleles for a single trait is said to be homozygous for that trait.

Homozygous mean a pair of alleles that are the same. Hence the root word homo- which means same. If the alleles were different, we would call this pairing a heterozygous pair, with the root word hetero- meaning different. An example of a homozygous pair would be AA, two dominant allele, or aa, two recessive alleles, while a heterozygous pair would be Aa, one dominant and one recessive allele.

Hetero means having two or more properties while hom-o means having one property.

An organism with two different alleles for a single trait is said to be heterozygous for that trait while an organism with only one type of allele is referred to as being homzygous.

Alleles are referred to as alternate forms of a gene. Phenotype can be defined as the expressed physical traits of an organism while Genotype is the genetic makeup of an organism which makes these options True
