Question

The allele for fangs (A) is dominant while the allele for no fangs (a) is recessive. A

dragon that is homozygous dominant for this trait will have what genotype and
phenotype combination?
O AA with no fangs
aa with no fangs
AA with fangs

Answer 1

AA with fangs

Step-by-step explanation:

As we saw in the question above, the dominant allele that characterizes the phenotype with fangs is represented by the letter A, while the recessive allele that characterizes the phenotype without fangs is represented by the letter a.

A homozygous individual is one that has two equal alleles (AA or aa), if the individual is a recessive homozygote he will present the "aa" alleles, if he is a dominant homozygote he will present the "AA" alleles. In the case of the question above, a dominant homozygous dragon, has AA alleles and therefore has the dominant phenotype, in this case, the coat will be "AA" with fangs

Answer 2

A dragon that is homozygous dominant for this trait will have "AA with fangs" genotype and phenotype combination.

Step-by-step explanation:

• An organism's unique genetic composition is understood as the genotype.

• In the term of Genotype, it can be defined as a combination of alleles of an individual organism whereas Phenotype is defined as the physical traits, both visible and measurable traits of an organism.

• Phenotype includes the properties like height, length, color of eyes, flower, skin, etc.
