The trait that is inherited out of the given options is freckles.
The correct answer is: a variant form of a gene.
The correct answer is: Each parent has two alleles per trait and passes one allele to their offspring.
In sexual reproduction, each parent contributes one copy of their alleles for each trait to their offspring. This means that offspring inherit one allele for each trait from each parent, resulting in a combination of genetic material from both parents.
What is an allele?(1 point)
Responses
a non-inherited trait
a non-inherited trait
a trait that appears in an offspring if one of the parents contributes it
a trait that appears in an offspring if one of the parents contributes it
a trait that can be masked

a variant form of a gene
A student claims that dominant traits are always the most common traits. Is this true? Why or why not?(1 point)
Responses
No, dominant traits only show up if they are inherited; how common they are is not influenced by this.

Yes, dominant traits became more common over time as they are passed down from generation to generation; recessive alleles continue to become less common over time.

No, dominant traits in general tend to be less common in the population and continue to persist only because they are dominant over more common recessive alleles.
No, dominant traits in general tend to be less common in the population and continue to persist only because they are dominant over more common recessive alleles.
Yes, dominant traits are called dominant because they are the most common.
Yes, dominant traits are called dominant because they are the most common.
The correct answer is: No, dominant traits in general tend to be less common in the population and continue to persist only because they are dominant over more common recessive alleles.
Dominant traits are not necessarily the most common traits. The frequency of a trait in a population is not determined by whether it is dominant or recessive. Dominance refers to the expression of a trait in the presence of other alleles. The frequency of a trait in a population is influenced by a variety of factors, including genetic drift, mutation, migration, and natural selection.
