Asexual- one parent, identical offspring
sexual- two parents, and non identical offspring
both- types of reproduction
Answer:
A) producing a litter of puppies by mating two dogs of different breeds
Explanation:
Answer:
- Diploid → Prophase, metaphase, and anaphase
- Haploid → Telophase
Explanation:
During prophase I, chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n
During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n
During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n
In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n
Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.
The two new cells are ready for meiosis II.
The correct answer is:
Nucleus
Prokaryotic cells do not contain <u>a nucleus</u>.
Recombination
: the process occurring in Meiosis I, in which offspring are able to obtain unique traits resulting in an array of different phenotypes (physical appearances).
Prophase I,
the homologous chromosomes line up in the middle of the cell and exchange segments of alleles, and then lining up in the cell in a NON-uniform way.... therefore resulting in genetically unique offsprings rather than identitical.
Mutations are result of evolutionary factors. They create genetic diversity that helps species adjust to different climates, behaviours and foods. Mutations that occur in a fit indivual can result in offspring that are genetically more successful in adjustments to different climates, foods, and environments.
All in all Recombination results in unique looking indivuals, whereas mutations result in greater survival chances of a species.
