The best answer would be <u>C) millions or billions of stars</u>.  Though, galaxies can vary drastically throughout the universe, so it is hard to estimate.  All of the visible galaxies we've observed are made up of millions, billions, or more stars. 

Hope this helps :)

for a particular flower the allele for red is domonaniant the allele for white is ressivepunnent square
Papessa [141]

Answer:

The correct answer will be option-The red and white flower alleles are co dominant.

Explanation:

The Mendel suggested that for any trait, the organism contains its alleles which could be dominant and recessive. But there are cases in which multiple alleles exist for the same trait which are neither dominant nor recessive.  

Two cases arise due to this in which both the dominant alleles co-exist and show their phenotype effect called "co-dominance" and when both alleles form a new phenotype called 'incomplete dominance".

In the given case, the self-pollination produces red, white and patched flowers as a result of co-dominance because both the alleles show the equal effect on the flower petals (mixed phenotype) and form a flower with red patches or spots on the flower.

Thus, the selected option is the correct answer.
