<span>While alien genomes may be constructed by completely different molecules (for example, silicon based life forms are a possibility rather than carbon) it is logical to assume that all life forms would have some sort of protective mechanism to prevent the degradation of DNA during replication. Essentially, to prevent mutations and rapid aging, DNA, alien or otherwise, would have some types of telomeres. They might either be long chains of repeated or irrelevant code or molecules that would not be easily corrupted.</span>

In cats the allele for short hair is dominant over the allele for long hair. A short haired male and long haired female have kit
SCORPION-xisa [38]

Answer:

Genotype of parents:                  Ss     x     ss

Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

Explanation:

In cats the allele for short hair is dominant over the allele for long hair. (SS or Ss for short hair; ss for long hair).

A short haired male and long haired female have kittens. Eight kittens have short hair and 3 have long hair.

For the parents to have been able to produce long haired offsprings, it means both parents possess one copy each of the recessive traits. Thus we have

Phenotype of parent: A short haired male and long haired female

Genotype of parents:                  Ss     x     ss

Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

The amount of starch formation represented by the arrow can be increased in the presence of which condition?
nika2105 [10]

During light condition, starch formation increases.

The amount of starch formation represented by the arrow can be increased in the presence of light because in the chloroplast of leaves, starch is synthesized during the day and degraded during the night.

<h3>What is starch?</h3>

Starch is a polysaccharides which is made up of a long chain of glucose. The sub units that for starch are glucose atom and we know that glucose is produced in the process of photosynthesis so we can conclude that during light condition, starch formation increases.
