A chromosome in G1 of the cell cycle
A replicated chromosome
A chromosome found outside the nucleus
A special region that holds two centromeres together
Another name for the chromosomes found in genetics
The complete complement of an organism's genes
A specific sequence of polypeptides within each cell
A specialized polymer of four different kinds of monomers
A specific segment of DNA that is found within a prokaryotic chromosome
An ordered display of chromosomes arranged from largest to smallest
Individuals reproducing asexually transmit 100% of their genes to their progeny, whereas individuals reproducing sexually only transmit 50%.
Asexual reproduction produces offspring that are genetically identical to the parents, whereas sexual reproduction gives rise to genetically distinct offspring.
Asexual reproduction involves a single parent, whereas sexual reproduction involves two.
Asexual reproduction only requires mitosis, whereas sexual reproduction always involves meiosis.
All of the above
The set of unique physical characteristics that define an individual
The collection of all the mutations present within a genome
A unique combination of chromosomes found in a gamete
A system of classifying cell nuclei
A display of every pair of homologous chromosomes within a cell, organized according to size and shape
Both present in every somatic cell of males and females alike.
Of approximately equal size.
Almost entirely homologous, despite their different names.
Called "sex chromosomes" because they determine an individual's sex.
All of the above
The species is diploid with 32 chromosomes.
The species has 16 sets of chromosomes.
There are 8 homologous pairs.
During the S phase of the cell cycle there will be 32 separate chromosomes.
A gamete from this species has 4 chromosomes.
An unfertilized egg cell
A sperm cell
A male somatic cell
A female somatic cell
Both A and D
In humans, each of the 22 maternal autosomes has a homologous paternal chromosome.
In humans, the 23rd pair, the sex chromosomes, determines whether the person is female (XX) or male (XY).
Single, haploid (n) sets of chromosomes in ovum and sperm unite during fertilization, forming a diploid (2n), single-celled zygote.
At sexual maturity, ovaries and testes produce diploid gametes by meiosis.
Sexual life cycles differ with respect to the relative timing of meiosis and fertilization.
Diploid, and the chromosomes are composed of a single chromatid.
Diploid, and the chromosomes are composed of two chromatids.
Haploid, and the chromosomes are composed of a single chromatid.
Haploid, and the chromosomes are composed of two chromatids.
Tetraploid, and the chromosomes are composed of two chromatids.
Two diploid cells result.
Four diploid cells result.
Four haploid cells result.
Four autosomes result.
Four chiasmata result.
The chromosomes condense.
The nuclear envelope disassembles.
A spindle forms.
Each chromosome is composed of two chromatids.
The random and independent way in which each pair of homologous chromosomes lines up at the metaphase plate during meiosis I.
The random nature of the fertilization of ova by sperm.
The random distribution of the sister chromatids to the two daughter cells during anaphase II.
The relatively small degree of homology shared by the X and Y chromosomes.
All of the above
Crossing over combines sections of the maternal and paternal chromosomes.
Crossing over plays a role in both sexual and asexual reproduction.
There are on average one to three crossover events per chromosome.
Crossing over increases the extent of genetic variation beyond what is possible through independent assortment alone.
Crossing over results in recombinant chromosomes.
Chromatids are attached to one another.
Metaphase chromosomes become aligned.
Chromosomes are grouped during telophase.
The nucleus is located prior to mitosis.
New spindle microtubules form.
