A trait appears in both men and women with equal frequency, and offspring can inherit the trait from the mother or the father. All affected individuals have at least one affected parent. This trait is autosomal dominant. X‑linked dominant. X‑linked recessive. autosomal recessive. Y‑linked.

Explanation:

As given here that;

A trait appears equally in both males and female, and offspring can inherit the trait both from father and mother, it indicates that this trait is not sex limited or sex linked.

And its also given that all effected individuals have at least one affected parent.

So lets parents as

A*a and A*a

so offspring are AA, Aa, Aa and aa.

If it is dominant trait, 3 out of 4 offspring are affected.

If it is recessive then 1 out of 4 offspring is affected, but here both the parents are unaffected, so it is autosomal dominant trait.

example 2; cross between aa×  Aa

offspring : Aa, Aa, aa, aa

3. AA× aa

Aa, Aa...

4. AA×  Aa.

AA ,Aa, AA, Aa

Explanation:

Autosomal dominant inheritance

In the given example, the occurrence of the trait in both sexes equally shows that the given trait is autosomal

Allele is passed from the affected parent to affected offsprings which shows that it is dominant and moreover all affected individuals have at least one affected parent, all this proves that the given trait is autosomal dominant

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
