Ivy Biology Mid Term Review

Front

What is incomplete dominance in flower inheritance?

Back

Incomplete dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a phenotype that is a blending of the two traits. For example, crossing yellow and red flowers produces orange flowers.

Front

What is the positive part of an atom?

Back

The positive part of an atom is the proton, which carries a positive charge.

Front

What is the energy molecule or cell's currency?

Back

The energy molecule or cell's currency is ATP (Adenosine Triphosphate), which stores and transfers energy within cells.

Front

When does crossing over occur in cell division?

Back

Crossing over occurs during Meiosis I, specifically in prophase I, where homologous chromosomes exchange genetic material.

Front

What does the Law of Segregation state?

Back

The Law of Segregation states that the two alleles for a single trait will separate randomly during gamete formation, resulting in a 50% chance for either allele to end up in a gamete.

Front

What is codominance in genetics?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that shows both traits distinctly, such as AB blood type.

Front

What is the role of neutrons in an atom?

Back

Neutrons are neutral particles found in the nucleus of an atom that contribute to the atomic mass and stability of the nucleus.

Front

What is the function of ATP in cellular processes?

Back

ATP provides energy for various cellular processes, including muscle contraction, nerve impulse propagation, and biosynthesis.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis is a process of cell division that results in two identical daughter cells, while meiosis is a specialized form of cell division that produces four genetically diverse gametes.

Front

What is the significance of the Law of Independent Assortment?

Back

The Law of Independent Assortment states that alleles for different traits are distributed to gametes independently of one another, leading to genetic variation.
