Cell cycle
Part of the cell cycle where cell division occurs
Mitosis
Is a type of cell division that produces haploid gametes in diploid organisms.
Meiosis
Mode of asexual reproduction where a piece of the body or fragment breaks up, giving a new organism.
Fragmentation
The genetic make up of an organism.
Genotype
The phenomenon in which two true-breeding parents crossed to produce an intermediate offspring
incomplete dominance
Number of cells resulting after cell division:
2
In this phase of mitosis chromosomes align at the equatorial plane of the cell.
Metaphase
The most important disadvantage of asexual reproduction, which can slow down evolution and kill an entire population.
The new individuals produced are genetically and physically identical to each other
Augustinian monk who used statistics to describe the inheritance patterns he observed in pea plants.
Gregor Mendel
Is seen when neither allele is recessive or masked by the other allele, both alleles are equally expressed.
codominance
Refers to the presence of a single set (not pairs) of chromosomes in an organism’s cells.
Haploide
In this phase of mitosis:
Spindle fibers dissasemble, nuclear membrane re-forms, chromosomes uncoil, nucleolus re-forms.
Telophase
Type of asexual reproduction where a parent cell divides, resulting in two identical cells, it happens mostly in bacteria.
binary fission
One of two or more versions of a genetic sequence at a particular region on a chromosome. An individual inherits two for each gene, one from each parent.
Allele
Inheritance occurs when there are more than two alleles that are possible to code for any one characteristic.
multiple alleles
This phase of the cell cycle is about growth and DNA synthesis.
Interphase or phase S
Is the process during which the cell contents are split between the two new daughter cells. The final division of the cell membrane.
cytokinesis
In this type of asexual reproduction an unfertilized egg makes a new organisms, it happens on bees.
Parthenogenesis
Observe the next punnet square:
g g
G Gg Gg
g gg gg
If G is for a green seed color and g is for a yellow seed color, which is the probability that the offspring will have yellow seed color?
50%
This statement of natural selection means that not all organisms can reproduce, those who survived are better suited for their environment and have more chances to expand their genetic traits in the population.
differential reproduction
The most studied tumor-supressor gene, which detects damaged DNA, it also triggers other proteins to become active and repair the DNA. It also can trigger apoptosis.
p53
How do we call when nonsister chromatids of each homologous pair of chromosomes exchange segments?
crossing over
Multiplication of a plant using cells from stem, leaves or roots
Vegetative propagation
if our first generation are both homozygous for flower colour purple (PP) and white (pp), which is the probability that the offspring will have white flower colour?
0%
This natural selection statement is related to the genetic diversity, therefore, not all organisms are the same and adapt differently to their environment.
