A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance.....?

Question

A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotypic ratio of:
a. 4 dominant : 0 recessive
b. 1 dominant : 3 recessive
c. 3 dominant : 1 recessive
d. 1 dominant : 1 recessive

Please help me with this.
Please explain how you got the answer and please tell me what the answer is. For example: B. 1 dominant : 3 recessive

THANK YOU FOR HELPING ME FOR ALL WHO HELPED!

Answer 1

the answer is C. These problems can easily be solved with a Punnett square. Basically you have a square chart with the genotypes of both parents on the sides, and then you fill it in. Like this,

.....A....a
A. AA Aa
a. Aa aa

Thus you have 1AA, 2Aa, and 1aa. Since A is completely dominant, the ratio of dominant to recessive will be 3:1

Answer 2

a million . Ya its A , because legumious plant harbours nitrogen fixing micro organism which will boost the fertility of soil with assistance from replacing atmospheric nitrogen into soluble nitrates. 2 a three i imagine its C Nuclear means does no longer produce any pollution or launch carbon dioxide and sulfur dioxide into the ambience. hence, it does no longer make a contribution to international warming or greenhouse. even with the actuality that The waste made out of the nuclear fission of uranium is poisonous , and fairly radioactive .... desire I actually have helped.

Answer 3

c) 3 dominant : 1 recessive
complete dominance means that if something is heterozygous like Bb you can not tell it apart from something that is BB.

... B b
B Bb Bb
b Bb bb
