Front

What is incomplete dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype that is a blend of the two alleles.

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is a Punnett square?

Back

A diagram used to predict the outcome of a particular cross or breeding experiment, showing the possible genotypes of offspring.

Front

What are genotypes?

Back

The genetic constitution of an individual, represented by the alleles inherited from the parents.

Front

What is the significance of temperature in gene expression?

Back

Certain genes can be activated or deactivated based on environmental factors like temperature, affecting traits such as fur color.

Front

What is DNA?

Back

Deoxyribonucleic acid, the molecule that carries the genetic instructions for life.

Front

What is mRNA?

Back

Messenger RNA, a type of RNA that conveys genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is tRNA?

Back

Transfer RNA, a type of RNA that helps decode mRNA sequences into proteins by bringing the appropriate amino acids.

Front

What is rRNA?

Back

Ribosomal RNA, a component of ribosomes that helps in the synthesis of proteins.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.
