Biology 100 2025/2026 Exam Questions
and Corresponding Answers with Surety
of 100% Pass Mark
Cell Cycle - 🧠 ANSWER ✔✔The series of events, that take place leading to the
creation of cells
Crossing over Fertilization - 🧠 ANSWER ✔✔Crossing over occurs during
prophase I of meiosis I. It involves the switching of genes between the non-sister
chromatids of homologues which allows the novel mixture of maternal and
paternal genetic material with new, recombinant
chromosomes.
Test Cross - 🧠 ANSWER ✔✔first introduced by Gregor Mendel, involves the
breeding of an individual with a phenotypically recessive individual, in order to
determine the zygosity of the former by analyzing proportions of offspring
phenotypes.

, Interphase in cell cycle - 🧠 ANSWER ✔✔the phase of the cell cycle in which a
typical cell spends most of its life. During this phase, the cell copies its DNA in
preparation for mitosis.
Cytokinesis - 🧠 ANSWER ✔✔the cytoplasmic division of a cell at the end of
mitosis or meiosis, bringing about the separation into two daughter cells.
Genes - 🧠 ANSWER ✔✔a unit of heredity that is transferred from a parent to
offspring and is held to determine some characteristic of the offspring.
Genome - 🧠 ANSWER ✔✔the haploid set of chromosomes in a gamete or
microorganism, or in each cell of a multicellular organism.
Homologous Chromosomes - 🧠 ANSWER ✔✔The cell has two sets of each
chromosome; one of the pair is derived from the mother and the other from the
father. The maternal and paternal chromosomes in a homologous pair have the
same genes at the same loci, but possibly different alleles.
Mitosis - 🧠 ANSWER ✔✔a type of cell division that results in two daughter cells
each having the same number and kind of chromosomes as the parent nucleus,
typical of ordinary tissue growth.
