BIO 180 EXAM Questions and Answers
(Top Grade Assured) 2026 Update
What is the haploid number? - Correct Answers ✅The
number of distinct chromosomes found in an organism.
What is ploidy? - Correct Answers ✅the number of
chromosome sets.
Haploid = 1
Diploid = 2
What is a chromosome? - Correct Answers ✅A long
continuous thread of DNA that consists of numerous genes.
What is a gene? - Correct Answers ✅the inherited
"instructions" for a trait that is found on a specific spot on a
specific chromosome. Diploid organisms carry 2 alleles for
each gene; one maternal and one paternal.
What is an allele? - Correct Answers ✅A specific seqeunce
of nucleobases (Adenine, Thymine, Cytosine and Guanine)
that determines the expression of the phenotype. Everyone
has the same genes but people can have diffrent alleles.
What is a trait? - Correct Answers ✅a specific
characteristic.

Name the phases of Mitosis in order. - Correct Answers
✅Interphase, Prophase, Metaphase, Anaphase, Telophase,
Cytokinesis.
What happens in Interphase 1 of meiosis? - Correct
Answers ✅The replcated DNA coils into chromesomes which
contain two identical sister chromatids connected by a
centromere. The centrioles also duplicate.
What happends during Prophase 1 of meiosis? - Correct
Answers ✅The homologous chromosomes synapse and
crossing over occurs. The centrioles move to the two poles of
the cell and extend spindle fibers.
What happends during Metaphase 1 of meiosis? - Correct
Answers ✅The synapsed homologs independantly assort
along the metaphase plate.
What happens during Anaphase 1 of meiosis? - Correct
Answers ✅The spindle fibers connect with the centromeres
and pull the homologs apart.
* When drawing, curve the chromesomes to show motion*
What happends during Telophase 1 of Meiosis? - Correct
Answers ✅The chromesomes are pulled to the far side of
the cell and the cell starts to split apart. Becasue of
