Answer:
Hybrids are the offspring of two species. A mule is the hybrid offspring of a female horse and male donkey. Because mules are sterile, they are not classified as a distinct species. The biological species concept connects the idea of a species to the process of evolution.
The given question is incomplete as the group of choices lack the correct answer, however, the correct group of choices are as follows:
A. Movement of sister chromatids to opposite poles at anaphase II of meiosis.
B. Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
C. Crossing over between homologous chromosomes during prophase I of meiosis.
D. Replication of chromosomes prior to meiosis.
E. Independent alignment of different homologous pairs on the metaphase I spindle.
Answer:
The correct answer is : Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
Explanation:
The Mendel's law of segregation says that during formation of gametes the copies of genes segregate from each other so each gamete has equal and only one allele of the gene.
This behavior of homologous chromosome can be seen in anaphase I in meiosis, responsible for the segregation of copies of allele into different copies.
Thus, the correct answer is : Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
<h3><u>Answer;</u></h3>
There will be <u>4 different combination of chromosomes</u>
<h3><u>Explanation;</u></h3>
- <em><u>A diploid cell is a cell that contains two sets of each chromosomes; thus a diploid cell with two pairs of homologous chromosomes has four chromosomes.</u></em>
- <u><em>Gametes are produced through meiosis which is the type of cell division in which a parent cells divides into four daughter cells each with half the number of chromosomes as the parent, that is the cell are haploid.</em></u>
- Therefore,<em><u> </u></em><em><u>a diploid cell with two pair of homologous chromosomes will produce four haploid cells after meiosis each with two chromosomes.</u></em>
