In alternation that generations, what is the diploid stage of a plant that follows fertilization called?


Identify all possible products of meiosis in plant and also animal life cycles.

You are watching: For what purpose(s) might a karyotype be prepared?

\"*\"

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?

n chromosomes

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


12.

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


13.

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


14.
