Non-Mendelian Genetics & Biotechnology

Front

What is codominance in genetics?

Back

Codominance is a form of inheritance where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive. An example is a flower with red and white spots.

Front

What are some useful traits that can be transferred through genetic engineering?

Back

Useful traits that can be transferred through genetic engineering include pest resistance, disease resistance, and drought tolerance.

Front

What does it mean if a population of organisms has no genetic variation?

Back

If there is no genetic variation in a population, it means that the organisms are clones, which are genetically identical to one another.

Front

What is DNA fingerprinting?

Back

DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles. It works because no two people, except identical twins, have exactly the same DNA.

Front

What is the significance of genetic variation in a population?

Back

Genetic variation is important for the survival of a species as it allows for adaptation to changing environments and helps prevent extinction.

Front

What is a transgenic organism?

Back

A transgenic organism is one that has been genetically modified to contain a gene or genes from another species.

Front

What is the role of biotechnology in agriculture?

Back

Biotechnology in agriculture is used to enhance crop yields, improve resistance to pests and diseases, and develop crops that can withstand environmental stresses.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles are expressed in the phenotype even when only one copy is present, while recessive alleles are only expressed when two copies are present.

Front

What is a hybrid organism?

Back

A hybrid organism is the offspring resulting from the crossbreeding of two different species or varieties.

Front

What is the purpose of genetic testing?

Back

The purpose of genetic testing is to identify genetic disorders, assess the risk of developing certain diseases, and guide treatment options.
