Genetics Review Flashcardizz

Front

What pattern of inheritance is shown in this image?

Back

Incomplete dominance: A genetic scenario where neither allele is completely dominant, resulting in a phenotype that is a blend of the two alleles.

Front

A characteristic that an organism can pass on to its offspring through its genes is ___________

Back

Trait: A specific characteristic of an organism, such as eye color or height, that is inherited from its parents.

Front

Which of the following genotypes is homozygous dominant?

Back

AA: A genotype consisting of two identical dominant alleles for a trait.

Front

What does homozygous mean?

Back

Homozygous: Having two identical alleles for a particular gene, often referred to as purebred.

Front

What is the probability of heterozygous offspring from a monohybrid cross?

Back

50%: In a typical monohybrid cross, there is a 50% chance of producing heterozygous offspring.

Front

What is a gene?

Back

Gene: A segment of DNA that contains the instructions for building a specific protein or trait.

Front

What is the difference between genotype and phenotype?

Back

Genotype: The genetic makeup of an organism; Phenotype: The observable characteristics or traits of an organism.

Front

What is codominance?

Back

Codominance: A form of inheritance where both alleles in a heterozygote are fully expressed, resulting in a phenotype that shows both traits.

Front

What is incomplete dominance?

Back

Incomplete dominance: A genetic situation where one allele does not completely dominate another, resulting in a third phenotype that is a blend of the two.

Front

What is an allele?

Back

Allele: Different forms of a gene that can exist at a specific locus on a chromosome.
