For the fly to pass on a specific trait to its offspring, a genetic change must occur, typically through mutations in its DNA. This alteration can affect the expression of genes related to the trait, enabling it to be inherited. If the change provides a survival advantage, it may become more prevalent in subsequent generations through natural selection. Thus, the trait can be passed down and potentially evolve over time.

What is a trait that will appear in yhe offspring if one of the parents contributes it?
In order for a recessive trait to appear in the offspring, it must inherit a recessive allele for that trait from both parents.
If an animal with 2 dominant genes for a trait has offspring with an animal with 2 recessive genes for same trait their offspring can only have what?
Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
IS IT POSSIBLE TO HAVE A RECESSIVE TRAIT APPEAR IN OFFSPRING IF THE GENOTYPE IS HETEROZYGOUS?
No, a heterozygous genotype, which consists of one dominant and one recessive allele (e.g., Aa), will typically express the dominant trait, not the recessive one. However, if both parents are heterozygous (Aa), there's a possibility for offspring to inherit two recessive alleles (aa), which would express the recessive trait. Thus, while a heterozygous individual cannot express a recessive trait, such traits can appear in their offspring if the right allele combinations occur.
What If parents supplied different alleles for a certain trait to their offspring terms would be used to describe the offspring?
If parents supply different alleles for a certain trait to their offspring, the offspring are described as heterozygous for that trait. This means they possess two different alleles, one inherited from each parent. In contrast, if the offspring received the same allele from both parents, they would be termed homozygous for that trait. The expression of the trait may depend on whether the alleles are dominant or recessive.
Do organisms that are purebred for a trait will express the same characteristics for many generations?
Yes, organisms that are purebred for a trait will generally express the same characteristics for many generations as long as there is no genetic mutation or environmental influence that causes a change in the trait. This is because purebred organisms have homozygous genotypes for that trait, resulting in consistent expression of the trait in offspring.
What is a trait that will appear in yhe offspring if one of the parents contributes it?
In order for a recessive trait to appear in the offspring, it must inherit a recessive allele for that trait from both parents.
How many phenotypes does each trait have?
the offspring have two factors for each trait
What is the visible trait an offspring exhibits called?
The visible trait an offspring exhibits is called the phenotype.
What is the likelihood that the offspring of individuals IV-3 and IV-4 will inherit the trait?
The likelihood that the offspring of individuals IV-3 and IV-4 will inherit the trait depends on the specific genetic inheritance pattern of the trait. If the trait is determined by a dominant gene, there is a 50 chance that the offspring will inherit the trait. If the trait is determined by a recessive gene, there is a 25 chance that the offspring will inherit the trait.
Two individuals heterozygous for a single trait have children what is the expected phenotypic ratio of the possible offspring?
Let T=trait (dominant) Let t= trait (recessive) Father has Tt and mother also has Tt The possible combinations for offspring are: TT Tt Tt and tt Therefore There is a 3/4 change of the offspring having the dominant trait and a 1/4 Chance of the offspring having the recessive trait It should also be noted that there is a 1/4 chance of the offspring carrying two dominant genes meaning that any of their children will also share the dominant trait
What is meant by recessive trait when discussing genetics?
When discussing genetics, recessive trait refers to the fact that the offspring of two parents must inherit two copies of a gene to expose the trait. This would mean that both parents must be carriers of said gene in order for their offspring to show a recessive trait.
Gregor Mendel concluded that a parent passes of the alleles for a trait to their offspring?
One of the allels for a trait to it's offspring.
How can offspring inherit a recessive trait?
An offspring can inherit a recessive trait if both of its parents are homozygous for the dominant allele.
If an animal with 2 dominant genes for a trait has offspring with an animal with 2 recessive genes for same trait their offspring can only have what?
Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
How do changes at the DNA and gene level change populations to eventually form new species?
I think you're talking about genetic mutation... If the trait is dominant then it will be spread to its offspring and if it doesn't hinder the offspring's survival then the trait will continue to be passed on to new generations.
In which offspring does a dominant trait appear?
A dominant trait will appear in offspring that inherits at least one copy of the dominant allele from either parent. If an individual has two different alleles for a trait (one dominant and one recessive), the dominant trait will be expressed.
What is the difference between the dominant and recessive allele for a trait?
An individual must have 2 recessive alleles in order for a trait to show up. One must only have 1 dominant allele in order for a trait to occur.
