Answer:
Dominant
Explanation:
A hybrid trait is also known as heterozygous, which is the combination of the dominant and recessive alleles of a gene. On the other hand, a purebred is combination of the same two dominant alleles or the same two recessive alleles. For example, in the gene coding for height, allele for tallness (T) is dominant over the allele for shortness (t).
A purebred for this trait will either be "TT" or "tt" while a heterozygous or hybrid will be Tt. Hence, according to this question, crossing of a hybrid (Tt) and a dominant purebred (TT) will always result in offspring which are DOMINANT (see attached image).
Answer:
The picture is just a black screen so I can’t see the question
I don't know but i think that the correct answer is that a long time ago the sea level was really high and mountains were under the sea and when the sea level got lower the mountains " got higher" and it took the fish with them
I would say d, they can’t move and they are remains from the past
Answer:
Gene flow
Explanation:
Gene flow describes the process where genetic information migrates to another population, introducing new alleles into the gene pool and increasing the variation in that population.
Having physical barriers would prevent this exchange of information. For example, two populations separated by a mountain range or body of water would have far less chances to interact and exchange genetic material. This would make it difficult for gene flow to occur.
