Example of a species is a donkey and a horse mate to produce a mule that is sterile and is unable to produce babies.
Explanation:
- Species is the group of organisms that interbreed or have the potential of interbreeding in nature.

- The organism that reproduce asexually cannot be mentioned under species.
- Some animals form naturally hybrid and mostly mate with their own groups.
- So donkey and horse mates to produce a new living, which is considered as the species.
Answer:
both A and C
Explanation:
To know whats happens with all the offspring and the probabilities you need to draw Punnett squares.
We will call T the dominant trait and t the recessive.
TT x tt = Tt Tt Tt Tt = 100% Tt
100% of the offspring will show the dominant allele.
Tt x Tt = TT Tt tT tt =25% TT 50% Tt 25% tt
Here, you have 25% chances that the offspring shows the recessive allele.
TT x TT = TT TT TT TT= 100% TT
100% of the offspring will show the dominant allele.
Tt x tt = Tt tt tt tt = 25% Tt 75% tt
Here, you have 75% chances that the offspring shows the recessive allele.
