Question

If a long tail is a dominant characteristic, in which case is the characteristic of a long tail definitely expressed?

when at least one parent has a long tail

when both parents have a long tail

when neither allele contains instructions for a long tail

when at least one allele contains instructions for a long tail

Answer 1

Answer:

When both parents have a long tail :)

Explanation:

the short tail trait is now recessive so it cant happen on its own. The offspring will most likely have a long tail just like thae parents :)

Answer 2

Answer:

When at least one allele contains instructions for a long tail

Explanation:

Gregor Mendel discovered that an organism receives two forms of a gene called ALLELE for a particular trait. Each allele encodes or represent a different trait in that same gene. However, according to Mendel, one allele called DOMINANT allele is capable of masking the expression of the other allele, called RECESSIVE allele. This means that in a heterozygous state i.e. combination of the two different alleles, the dominant trait encoded by the dominant allele will always be expressed.
