Yup!! After a long duration...... Mutations lead to evolution because if the mutation is favorable then it will survive and pass on its traits.
Probability is 1/4 as the possible outcomes would be 1/4 homozygous dominant, 1/2 heterozygous, and your answer 1/4 homozygous recessive

True, The sun grows the energy we need when I say that I mean without the sun we wouldn't have plants to eat or food to survive on. When we eat the plants or animals we take the energy they had in their body and then it goes to ours.
Answer:
The chance of a woman with an AB blood type and a man with an O blood type having a child with O blood is 0%.
Explanation:
A mother with blood type AB (AB) will pass either antigen A or antigen B to the offspring, while the father with blood type O (OO) will not pass any antigen.
The result of an AB X OO cross would be
Alleles O O
A AO AO
B BO BO
For this reason, the offspring of this couple will be
- <em>Blood type A (AO) 50%.
</em>
- <em>Blood type B (BO) 50%.
</em>
- <em>Blood type O (OO) none.
</em>
Heredity of blood type depends on the presence of surface antigens on the erythrocyte membrane. Blood type O occurs in persons whose red blood cells do not possess surface antigens A or B.
Surface antigens are what determine blood type, so
:
- <em>The presence of antigen A determines blood type A.
</em>
- <em>Blood type B depends on the presence of antigen B.
</em>
- <em>Blood type AB has both antigens.
</em>
Blood type O has no antigens, and for blood type O to manifest, it must have both alleles for O.
A mother AB and father O cannot have offspring with blood type O.
