Genes have different forms, called
answers:
A) alleles.
B) traits.
C) phenotypes.
D) genotypes
A) alleles.
The correct answer is A) alleles.
The correct answer is A) alleles.
To arrive at this answer, it helps to have a basic understanding of genetics. Genes are segments of DNA that contain the instructions for building and functioning of organisms. They determine specific traits, such as eye color, height, or hair type. However, genes can have different versions or forms, which are called alleles. Alleles are alternative variations of a gene that can exist at the same location on homologous chromosomes.
Traits (Option B) refer to the observable characteristics or attributes of an organism, which are determined by the combination of genes and environmental factors.
Phenotypes (Option C) are the physical or observable expressions of genes and environmental influences. They represent the traits or characteristics that can be seen or measured, such as eye color, hair type, or blood type.
Genotypes (Option D) represent the genetic makeup of an organism, which refers to the specific combination of alleles it possesses for a particular trait. Genotypes can be represented by the combination of letters or symbols that represent the alleles inherited from both parents.
In summary, while traits, phenotypes, and genotypes are related concepts in genetics, alleles specifically refer to the different forms or versions of a gene.
