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 would the offspring most likely be if an individual with a heterozygous trait and an individual with a homozgous recessive trait crossed be?
The offspring would have a 50% chance of being heterozygous and showing the dominant trait and a 50% chance of being homozygous for the recessive trait.
A trait that appears or is expressed in the f1 generation is what?
A trait that appears or is expressed in the F1 generation is considered dominant. Dominant traits will manifest themselves in the offspring when at least one parent carries the dominant allele for that trait.
What does the word dominant mean in genetics?
In genetics, "dominant" refers to an allele that will be expressed in the phenotype if present, masking the expression of the corresponding recessive allele. This means that even if an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele's phenotype will be visible.
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
A parent that is homozygous for a dominant trait is crossed with a parent that is homozygous for the recessive trait What percentage of the offspring will display the dominant trait?
100% of the offspring will display the dominant trait because the homozygous dominant parent can only pass on the dominant allele. The offspring will inherit one dominant allele from the dominant parent and one recessive allele from the recessive parent, resulting in a heterozygous genotype expressing the dominant trait.
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.
What does Gregor Mendel law of dominance state?
Mendel's law of dominance states that if you have a pair of genes then the one that shows up in the offspring is most likely the dominant gene because the dominant is passed along more often than the recessive.
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 would the offspring most likely be if an individual with a heterozygous trait and an individual with a homozgous recessive trait crossed be?
The offspring would have a 50% chance of being heterozygous and showing the dominant trait and a 50% chance of being homozygous for the recessive trait.
Which type of genetic trait appears in every generation of offspring?
A dominant genetic trait appears in every generation of offspring because only one copy of the dominant allele is needed for the trait to be expressed.
Is a widows peak dominant or recessive?
A widow's peak is a dominant trait. This means that if one parent has a widow's peak, there is a higher likelihood that their offspring will also inherit this trait. If both parents have a widow's peak, the offspring will most likely have one as well.
What is the percentage of offspring that will exhibit the dominant trait from A crossing of A homozygous dominant and homozygous recessive individual?
The homozygous dominant individual can only pass on the dominant allele and the homozygous recessive individual can only pass on the recessive allele, therefore all offspring will be heterozygous and have the dominant phenotype.
Can a white offspring be a hybrid why?
If the white trait is dominant, then yes. If the white trait is recessive, then no.
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.
What is a dominant trait when a red eyed fly mates with a blue eyed fly resulting in offspring that all have red eyes?
It is likely that the red eye trait is dominant if a red eye and blue eye fly have only red eyed offspring. However, it is possible that the blue eyed trait is dominant and the blue eyed fly has the red eyed gene and passed it on to its offspring every time.
A trait is inherited in an autosomal dominant manner If two individuals that do not have the trait mate what percentage of their offspring would be expected to have the trait?
0. Unless there is a germline mosaicism or sporadic mutation in the fertilized embryo.
