Answer: This is a case of incomplete dominance inheritance because we can asume that the tail length is a trait with 2 alleles (no tail and long), but is posible to see 3 fenotypes, long, no tail, and medium which can be consider as a half way between long and no tail.
The phenotypes that seem a mix of two traits have heterozygous genotype, in this case the two parental cats have genotype Ll (assuming L as the symbol for long tail) since they have medium tails
When 2 heterozygous individual cross, the proportions according to Mendel's laws is:
25% offspring: Homozygous dominant
25% offspring: Homozygous recesive
50% offspring: Heterozygous
This proportions are quit similar to those obtained in the exercise
2/11 = 18 % Long tail: LL
3/11 = 27% No tail: ll
6/11 =54% Medium tail: Ll
Answer:
we can find such type of genetic disorders through pedigree chart.
Explanation:
cystic fibrosis is a Autosomal recessive disease
Muscular dystrophy is a Autosomal dominant disease.we can see them by observing the next generations going on .we can't find them in person's DNA fingerprint profile.
Water shortage can also know as Water scarcity is the lack of fresh water resources to meet the standard water demand. Humanity is facing a water crisis, due to unequal distribution resulting in some very wet and some very dry geographic locations, plus a sharp rise in global freshwater demand in recent decades driven by industry.
a lack of permanently frozen soil.
Explanation:
Conifer trees dominate boreal forests rather than tundra because of a lack of permanently frozen soil.
Tundras have permanently frozen soil and cannot support plant life to a very large extent.
- These frozen soils are called permafrost.
- Permafrost are soils that have remained frozen for more than two years.
- Plants require nutrients, water, air and organic matter from the soil to function and carryout their own life processes.
- In a tundra, these materials are held and trapped in the freeze.
- Therefore, like any other plants that have not adapted to this severe condition, they cannot grow well in this biome.

Answer:
Astronomers can use telescopes to look at very distant galaxies. This is how they see what the Universe looked like a long time ago. This is because the light from distant parts of the Universe takes a very long time to reach us. From these observations, it seems the physical laws and constants of the Universe have not changed.
Physicists are currently unsure if anything existed before the Big Bang. They are also unsure whether the size of the Universe is infinite.
