Look in ~ the cell in the figure. Based upon this figure, i beg your pardon of the following statements is true?
It is difficult to tell even if it is the cell is haploid or diploid.
This cell is diploid.
This cell is haploid.
What is the ideal evidence telling you whether this cell is diploid or haploid?
The cabinet is haploid since the chromosomes are not discovered in pairs.
The cell is diploid because it contains two set of chromosomes.
The cell is diploid because each chromosome is composed of 2 chromatids
This chromosome has two chromatids, joined at the centromere. What procedure led to the development of the two chromatids?
The two chromatids were created by synapsis and also the development of a synaptonemal complex.
The two chromatids were developed by fertilization, bringing together maternal and also paternal chromatids.
The 2 chromatids were formed by duplication of a chromosome.
Two sister chromatids space joined at the centromere before meiosis. Which statement is correct
These chromatids comprise a diploid chromosome.
The cabinet that has these sisters chromatids must be haploid.
Barring mutation, the two sister chromatids have to be identical.
Asexual reproduction _____.
is restricted to plants
produces offspring genetically identical to the parent
is restricted to single-cell organisms
requires both meiosis and also mitosis
leads come a lose of genetic material
What number and varieties of chromosomes are discovered in a person somatic cell?
44 autosomes and 2 sex chromosomes
22 autosomes and 1 sex chromosome
21 autosomes and also 2 sex chromosomes
45 autosomes and also 1 sex chromosome
For what purpose(s) could a karyotype be prepared?
for prenatal screening, to determine if a fetus has actually the correct number of chromosomes
to recognize whether a fetus is masculine or female
to recognize the feasible presence the chromosomal abnormalities such together deletions, inversions, or translocations
The first and second answers space correct.
The an initial three answers are correct.
How are sister chromatids and also homologous chromosomes various from each other?
They space not different. Homologous chromosomes and sister chromatids are both identical copies of each other.
Homologous chromosomes save on computer the exact same gene loci yet may have various alleles that a specific gene.
Sister chromatids are identical copies of every other created during DNA replication.
Homologous chromosomes space identical copies of every other. One sister chromatid originates from the father, and also one comes from the mother.
Sister chromatids are just formed throughout mitosis. Homologous chromosomes are formed during meiosis.
Homologous chromosomes room closely associated with each various other in both mitosis and also meiosis. Sisters chromatids are only associated with every other throughout mitosis.
Homologous chromosomes save the exact same gene loci yet may have various alleles the a details gene. Sister chromatids are identical duplicates of every other developed during DNA replication
Mitosis results in the formation of how many cells; meiosis outcomes in the development of how many cells?
four diploid cells ... 4 haploid cells
two diploid cell ... 2 haploid cells
four haploid cells ... 2 diploid cells
two diploid cell ... 4 haploid cells
two diploid cells ... 2 diploid cells
2 dipoid...4 haploid
What is cross over?
the movement of genetic material native one chromosome to a nonhomologous chromosome
making an RNA copy the a DNA strand
the exchange the homologous parts of nonsister chromatids
a direct repercussion of the separation that sister chromatids
also referred to as the \"independent assortment that chromosomes\"
The exchange the homologous portions of nonsister chromatids
Heritable variation is compelled for i beg your pardon of the following?
the production of a clone
A human being cell comprise 22 autosomes and a Y chromosome is
a somatic cabinet of a male.
a somatic cell of a female.
Homologous chromosomes relocate toward opposite poles that a dividing cell during
. Binary fission
