Biology 100 Questions and Correct
Answers/ Latest Update / Already Graded
Cell Cycle
Ans: The series of events, that take place leading to the
creation of cells
Crossing over Fertilization
Ans: 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
Ans: 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

, Page |2
Ans: 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
Ans: the cytoplasmic division of a cell at the end of mitosis or
meiosis, bringing about the separation into two daughter cells.
Genes
Ans: a unit of heredity that is transferred from a parent t o
offspring and is held to determine some characteristic of the
offspring.
Genome
Ans: the haploid set of chromosomes in a gamete or
microorganism, or in each cell of a multicellular organism.
Homologous Chromosomes
Ans: 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.
