Answer:
- Independent assortment of chromosomes
- Crossing over
Explanation:
Independent assortment of chromosomes
We each have a diploid genome that is used to make haploid gametes. The selection of which combinations of chromosomes (and the particular alleles they hold) that are passed on to the gametes is random. I.e. 1 gamete could have the paternal chromosomes 1, 4, and 6, and maternal 2, 3 and 5. Another gamete could have paternal 2, 4, and 6, and maternal 3 2 and 5.
This produces unique combinations of alleles that are passed onto the next generation after sexual reproduction.
Crossing over
Crossing over occurs when homologous chromosomes pair up and align during meiosis. When this happens, they can exchange genetic material at homologous sites. This means that even <em>within </em>chromosomes, there are new combinations of alleles being created to pass on to the gametes before sexual reproduction. That is, each chromosome will have chunks of maternal and chunks of paternal DNA.
Both of these features increase genetic variation by two mechanisms, and this is occurring in two individuals, producing genetically diverse offspring.
Answer:
Both are cells and one is older than the other
Explanation:
<span>Traits such as hair color, height, and other appearances are inherited. Traits are based on a mixture of the DNA that comes from your parents. Some traits however can be affected by outside factors such as environment and nourishment. as an example, children who are malnourished tend to be smaller than children who are not.</span>
The scale used to measure the intensity of ice storms is called the Sperry–Piltz Ice Accumulation Index, <span>based on the expected footprint of an ice storm, the expected ice accumulation as a result of a storm, and the expected damage a storm inflicts on human-built structures.
Meteorologists use Dual Polarization Radar, and the Q2 a mix of sensors and algorithms to predict precipitation.
Yes ice storms can be predicted by weather agencies, and it depends how fast it is detected and how severe it is.
