Answer:

The correct answer is main sequence stars.

Explanation:

The H-R diagram refers to the graphical apparatus, which are used by the astronomers to categorize stars on the basis of their spectral type, luminosity, stage of evolution, color, and temperature. The classification of the majority of the stars on the H-R diagram is the main sequence stars.  

Approximately 90 % of the stars found in the universe, comprising the Sun refers to the main sequence stars. These stars can vary from about the tenth of the Sun's mass to about 200 times.

In rabbits, short hair(S) is dominant over long hair(s). What genotype and phenotype ratios are expected from a cross between tw
SOVA2 [1]

Answer:

Genotype                  Phenotype                      

SS                 1/4          Short hair         3/4

Ss                 2/4         Short hair          3/4

ss                  1/4          Long hair          1/4

Explanation:

Both are heterozygous for the trait so we can expect that the cross would be:

Ss x Ss

    S     s

S  SS   Ss

s   Ss   ss

So the resulting off-spring would have the following genotype and phenotype:

1 out of 4 will have a genotype of SS.

2 out of 4 or half will have a genotype of Ss.

1 out of 4 will have a genotype of ss.

But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:

Short hair: 1/4 + 2/4 = 3/4

Long hair:  1/4

So in summary:

Genotype                  Phenotype                      

SS                 1/4          Short hair         3/4

Ss                 2/4         Short hair        

ss                  1/4          Long hair          1/4
