A) chromosome replication B) synapsis occursC) production of daughter cells D) alignment that chromosomes at the equator E) condensation the chromatin


In alternation the generations, what is the diploid phase of a tree that adheres to fertilization called?


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

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

Gametes

Spores

Multicellular adult organisma


*

Look in ~ the cabinet in the figure. Based upon this figure, i beg your pardon of the complying with statements is true?

It is difficult to tell even if it is the cabinet is haploid or diploid.

This cell is diploid.

This cell is haploid.


*

What is the ideal evidence telling you even if it is this cell is diploid or haploid?

The cell is haploid since the chromosomes space not found in pairs.

The cabinet is diploid since it has two set of chromosomes.

The cabinet is diploid because each chromosome is composed of two chromatids


*

This chromosome has actually two chromatids, join at the centromere. What procedure led to the development of the 2 chromatids?

The two chromatids were formed by synapsis and the development of a synaptonemal complex.

The two chromatids were formed by fertilization, bringing together maternal and paternal chromatids.

The 2 chromatids were developed by duplication of a chromosome.


Two sister chromatids space joined at the centromere prior to meiosis. I beg your pardon statement is correct

These chromatids consist of a diploid chromosome.

The cabinet that includes these sisters chromatids need to be haploid.

Barring mutation, the 2 sister chromatids must be identical.


Asexual reproduction _____.

is minimal to plants

produces offspring genetically identical to the parent

is restricted to single-cell organisms

requires both meiosis and also mitosis

leads to a loss of hereditary material


What number and species of chromosomes are found in a person somatic cell?

n chromosomes

44 autosomes and also 2 sex chromosomes

22 autosomes and 1 sex chromosome

21 autosomes and 2 sex chromosomes

45 autosomes and also 1 sex chromosome


For what purpose(s) could a karyotype be prepared?

for prenatal screening, to identify if a fetus has the correct number of chromosomes

to determine whether a fetus is male or female

to recognize the possible presence the chromosomal abnormalities such together deletions, inversions, or translocations

The first and 2nd answers are correct.

The an initial three answers are correct.


How are sister chromatids and homologous chromosomes various from every other?

They space not different. Homologous chromosomes and sister chromatids room both identical duplicates of each other.

Homologous chromosomes save on computer the exact same gene loci yet may have different alleles of a specific gene.

Sister chromatids space identical duplicates of each other created during DNA replication.

Homologous chromosomes are identical duplicates of each other. One sister chromatid originates from the father, and one originates from the mother.

Sister chromatids are only formed throughout mitosis. Homologous chromosomes room formed throughout meiosis.

Homologous chromosomes space closely connected with each other in both mitosis and meiosis. Sister chromatids room only linked with each other throughout mitosis.


Homologous chromosomes save the very same gene loci yet may have different alleles that a certain gene. Sisters chromatids room identical copies of every other developed during DNA replication


12.

Mitosis results in the development of how many cells; meiosis results in the formation of how numerous cells?

four diploid cell ... 4 haploid cells

two diploid cells ... Two haploid cells

four haploid cell ... Two diploid cells

two diploid cell ... 4 haploid cells

two diploid cells ... Two diploid cells


2 dipoid...4 haploid


13.

What is crossing over?

the motion of genetic material native one chromosome to a nonhomologous chromosome

making one RNA copy of a DNA strand

the exchange that homologous sections of nonsister chromatids

a direct an effect of the separation the sister chromatids

also referred to as the "independent assortment of chromosomes"


The exchange of homologous sections of nonsister chromatids


14.
