Heredity Period 3

Front

What is selective breeding?

Back

A form of biotechnology where humans breed organisms of the same species for specific desirable traits.

Front

What is the genotype for a heterozygous organism?

Back

Rr

Front

What does the peppered moth example illustrate in natural selection?

Back

It illustrates how environmental changes can lead to changes in species through natural selection.

Front

What is the probability of two heterozygous green tree frogs producing offspring with short tongues?

Back

25%.

Front

What is natural selection?

Back

The process where organisms that are best suited to their environment tend to survive and reproduce more often.

Front

Define genotype.

Back

The genetic makeup of an organism, represented by letters (e.g., RR, Rr, rr).

Front

What is phenotype?

Back

The observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is the difference between dominant and recessive traits?

Back

Dominant traits are expressed when at least one dominant allele is present, while recessive traits are expressed only when two recessive alleles are present.

Front

What is hybridization?

Back

The process of breeding two different species or varieties to produce a hybrid.

Front

What is the significance of allele frequency in a population?

Back

It helps to understand how common a particular allele is in a population, which can indicate genetic diversity.
