Front

What is codominance in genetics?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in a phenotype that is neither dominant nor recessive. An example is the color patterns in certain angelfish.

Front

What is the genotype of a homozygous dominant individual?

Back

A homozygous dominant individual has two identical dominant alleles for a trait, represented as 'AA'.

Front

What is the expected percentage of offspring with achondroplasia from a cross between a homozygous dominant (AA) and a homozygous recessive (aa) individual?

Back

100% of the offspring will have the genotype 'Aa' and will express the trait of achondroplasia.

Front

What are the taxonomic classifications in biology?

Back

Taxonomic classifications are hierarchical categories used to organize and categorize living organisms, including levels such as domain, kingdom, phylum, class, order, family, genus, and species.

Front

Which two species are most closely related based on taxonomic classification?

Back

Species that share the same genus are most closely related. For example, Northern leopard frog and bullfrog are closely related.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell, essential for growth and repair.

Front

What are the stages of mitosis?

Back

The stages of mitosis include prophase, metaphase, anaphase, and telophase.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, reducing its concentration and producing oxygen.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.
