Crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.

<h3>WHAT IS MEIOSIS?</h3>

Meiosis is the process whereby a single cell produces four daughter cells that are genetically different from one another.

Meiosis is able to ensure genetic diversity in the daughter cells due to a process called Crossing over.

Crossing over is the exchange of genetic material between the non-sister chromatids of homologous chromosomes. It occurs in the prophase I stage of meiosis.

Therefore, crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.

muminat

Answer:

The correct option is B.

Explanation:

Muscle tissues of the heart refers to a group of cells that are carrying out similar functions in the heart. There are three different types of muscles, these are skeletal, cardiac and smooth muscles. The cardiac muscles are found in the heart, they form the contractile wall of the heart. These muscle contract involuntarily ( that is, without any external stimulation) and they are single nucleus, striated and short.

4. Describe similarities and/or differences in compartmentalization between prokaryotic and eukaryotic cells. 5. Sketch the proc
Mrac [35]

Answer:

Eukaryotes:

-Organisms with a well defined nucleus are known as eukaryotes. such cells are called as eukaryotic cells.

- Their nucleus is enclosed within the nuclear membrane.

- They do not posses a mitochondria.

- The cell wall is the outer most layer of a eukaryotic cell (only plant cells have a cell wall)

- The cells are divided by a process called mitosis.

Eg: Plants, Animals.

Prokaryotes:

- Organisms without a well defined nucleus are known as prokaryotes. Such cells are called as Prokaryotic cells.

- They lack nuclear membrane.

- Mitochondria, Golgi bodies, chloroplast and lysosomes are absent.

- The genetic material (DNA) is present on the chromosome.

Eg: Every organism coming under the kingdom monera.

Bengal Tigers (Panthera tigris tigris) have coat colors that are either golden (the dominant trait) or white. In examining a pop
Hoochie [10]

Answer:

5%

Explanation:

Frequency of white tigers = 4%

population of tigers = 200

number of heterozygotes = 10

<u>Determine the actual genotype frequency of Heterozygotes </u>

frequency of heterozygotes = Number of heterozygotes / population

= ( 10 / 200 ) * 100

= 0.05 * 100 = 5%
