How can two parents with a dominant trait like a widow's peak have a child with a recessive straight hairline?
Yes, because they can carry the trait from their parents.
You would need to look at the grandparents on both sides. If one grandparent on the maternal and one on paternal side had a widows peak then the parents could both be a carrier to the widow peak gene (wW), meaning they could produce a child with a widows peak. However, if both the maternal and or paternal grandparents lack a widows peak then it is impossible for a grandchild to have a widows peak because both parents would be recessive ww (straight hairline).
When attempting to figure out genetics it is best to observe three generations for family genetic traits. However, when in doubt you should confirm with a paternity test.
What else can I help you with?
Both parents are heterozygous widows peak is dominant over straight hair what kind of hairline would offspring have?
The offspring could have either a widow's peak if they inherit the dominant widows peak allele from at least one parent, or a straight hairline if they inherit the recessive straight hair allele from both parents. The genotype of the parents will determine the possible genotypes and resulting hairlines of the offspring.
Do Parents with the dominant phenotype cannot have offspring with the recessive phenotypeous for a trait that is?
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
What determines whether a person will have dominant or recessive hair color?
Hair color is determined by genes inherited from parents. Dominant genes for hair color will be expressed over recessive genes, resulting in the dominant color being displayed. If both parents pass on recessive genes, the recessive color will be seen.
A widow's peak is a V-shaped area of the hairline in the center of the forehead The allele for having a widow's peak is dominant to the allele for not having a widow's peak If two parents do not hav?
If two parents do not have a widow's peak, it is possible for their child to inherit a widow's peak if they both carry the dominant allele for it. This would mean that both parents are heterozygous for the widow's peak trait.
What is a reccessive trait?
the characters and habits that the offspring does not carry of the parents is known as recessive characters. example-woman-curl hair and fair body man-straight hair and black body. offspring-curl hair and black body in the above example, fair body and straight hair are the recessive characters that the child does not carry.
Tthe probability that two heterozygous parents for widow's peak will have a child with a straight hairline is what percent?
In genetics, widow's peak is typically represented as a dominant trait (W), while a straight hairline is recessive (w). If both parents are heterozygous (Ww), their offspring can be represented by a Punnett square, which shows the possible genotypes: WW, Ww, Ww, and ww. Only the ww genotype results in a straight hairline, which occurs in 1 out of 4 possibilities. Therefore, the probability that two heterozygous parents will have a child with a straight hairline is 25%.
Both parents are heterozygous widows peak is dominant over straight hair what kind of hairline would offspring have?
The offspring could have either a widow's peak if they inherit the dominant widows peak allele from at least one parent, or a straight hairline if they inherit the recessive straight hair allele from both parents. The genotype of the parents will determine the possible genotypes and resulting hairlines of the offspring.
Do Parents with the dominant phenotype cannot have offspring with the recessive phenotypeous for a trait that is?
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
Is it possible to have a dominate recessive trait?
no, because dominant is different from recessive, its impossible to have a dominant-recessive trait because the dominant is when only one copy of the gene is present, while in the recessive a trait that must be contributed by both parents in order to appear in the offspring, in short the dominant is for single parent, while in the recessive is a product of two parents.
How is Dominant and Recessive differ?
Dominant traits are expressed when just one copy of the gene is present, while recessive traits require two copies to be expressed. Dominant traits mask recessive traits when they are both present.
What determines whether a person will have dominant or recessive hair color?
Hair color is determined by genes inherited from parents. Dominant genes for hair color will be expressed over recessive genes, resulting in the dominant color being displayed. If both parents pass on recessive genes, the recessive color will be seen.
A widow's peak is a V-shaped area of the hairline in the center of the forehead The allele for having a widow's peak is dominant to the allele for not having a widow's peak If two parents do not hav?
If two parents do not have a widow's peak, it is possible for their child to inherit a widow's peak if they both carry the dominant allele for it. This would mean that both parents are heterozygous for the widow's peak trait.
When using a pedigree chart you can distinguish between recessive and dominant traits because?
The two most straight forward ways are: - If both parents have the trait, and one of their children does not, it must be recessive. - If neither parent has the trait, and one of their children does, it must be dominant.
Predict what genotype the children will have if one parent is homozygous recessive for earlobes and homozygous dominant for hairline (eeWW) and the other parent is homozygous dominant for unattached earlobes and homozygous recessive for hairline (EEww )?
The only possible outcome is EeWw, which will express the dominant genes but carry the recessive ones. They get one chromosome from each parent, but since the parents all have matching chromsomes in this case then it doesn't matter which one they get. Since one parent has EE, E is the only one that can be passed on. Since the other has ee, they can only pass on e. Therefore, the child can only possible have Ee, as they get one from each parent.
The probability of a homozygous recessive offspring resulting from a cross between two homozygous dominant individual is?
It depends on the parents. The parent could have two dominant genes which would give a 0% chance of the offspring being recessive. The only way that the offspring could have a recessive characteristic is if the both parents have one dominant and one recessive gene, a 25% chance. The chance that both parents would pass on the recessive gene (if they have one dominant and recessive gene) is also 25%, because there is a 50% chance for each parent.
A student inherited a recessive phenotype of a particular characteristics. however both the parents are phenotypically dominant for the characteristics. explain.?
The student inherited a recessive phenotype because both parents are likely heterozygous for that trait, meaning they carry one dominant allele and one recessive allele (e.g., Aa). Although they display the dominant phenotype, they can still pass on the recessive allele to their offspring. If the student received the recessive allele from both parents (aa), they will express the recessive phenotype despite the parents being phenotypically dominant. This scenario illustrates the principles of Mendelian genetics and inheritance patterns.
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.
