Answer:
Alleles are each of two or more alternative forms of a gene that are found at the same position in a chromosome. Traits on the other hand, are the characteristics that are defined by genes. ... For example, the gene that codes for the shape of a pea has two alleles, wrinkled and round.

The probability of the mother to pass down an abnormal long chromosome 13 is of
. The probability of the father to pass down an abnormal short chromosome 11 is also of
.
When meiosis occurs in order to produce gametes, firstly there is the separation of the two homologous chromosomes, leading to the formation of two cells with only n chromosomes. After this first division, another division happens over these two newly formed cells segregating the two sisters chromatids of each chromosome into two new cells again. In the end, there are 4 gametes formed where 2 have a copy of the same chromosome and the other two of a copy of the homologous chromosome. So, when forming gametes, both this man and woman, would create half gametes with an abnormal chromosome.
So, the probability of producing an offspring that will have both a long chromosome 13 and a short chromosome 11 is found by multiplying both probabilities of each individual parent passing the abnormal chromosome.
×
=
The probability is of
or 25%.
If such a child is produced, the probability that this child would eventually pass both abnormal chromosomes to one of his or her offspring is of
as well. Going back to the meiosis, the possible four gametes that could result from one of this individual's meiosis were either 2 with both abnormal chromosomes and 2 with both normal chromosomes, if the chromosomes were segregated together to the same cell, or all 4 with an abnormal chromosome and a normal chromosome, if the chromosomes were segregated separately to different cells. Considering this 8 possible resulting cells and only 2 of them having both the abnormal chromosomes we may conclude that
=
is the probability that this child would eventually pass both abnormal chromosomes to one of his or her offspring.

HEY MATE HERE IS YOUR ANSWER
1)Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.
2)While a landslide occurs when loose dirt or sediment falls down a slope, a rockslide occurs only when solid rocks are transported down slope. ... Fast-flowing rock slides or debris slides behave similarly to snow avalanches, and are often referred to as rock avalanches or debris avalanches.
3)The ten most important landslide events of 2018
The Palu earthquake – three flowslides and a landslide-induced tsunami in Indonesia.
The Anak Krakatau landslide and tsunami in Indonesia. ...
Landslides triggered by the Papua New Guinea earthquake. ...
Landslides triggered by the Hokkaido earthquake in Japan. ..
Explanation:
Insects, and some other invertebrates, exchange oxygen and carbon dioxide between their tissues and the air by a system of air-filled tubes called tracheae. Tracheae open to the outside through small holes called spiracles.
