Is widows peak a dominant or recessive trait?
Phenotype is what you physically see.
Which allele is recessive and which is dominant in the abbreviation Bb?
B is dominant and b is recessive.
Who has the longest widows peak?
I do.
Is angel man recessive or dominant?
recessive
Is a disorder know as a dominant or recessive?
Dominant disorders can be passed onto the offspring if the dominant gene is present in the offspring.
Is widows peak a dominant or recessive trait?
Phenotype is what you physically see.
Is a widows peak a trait controlled by many genes?
A widows peak is controlled by one gene that is passed on from both parents. In this case lets say your parents both have a dominant allele for a widows peak(A) so in that case, you would have a 100% chance of being born with one.
What One recessive and one dominate allele?
A dominant allele could be right handedness, or a straight hairline. A recessive allele could be freckles, a widows peak, clef chin, or left handedness.
What are genotype determinants?
'Genotype determinants' are just another set of words to describe alleles, because an allele is what determines your genes. An allele is basically an alternative forms of a gene. Humans have 2 forms (2 alleles) for each gene (except in sex cells) one from your mom, one from your dad. The allele occupies a fixed position (locus) on the chromosome and, depending on whether or not it is dominant or recessive, it determines the phenotypes- or how the gene will be physically expressed. A Example of recessive alleles: widows peak- you need two 'widows peak' alleles to have that feature physically expressed. If you have 1 widows peak allele and another for 'no widows peak' then the dominant form will be expressed, in this case it means you will not have a widows peak.
What Nationality of people has a dominant gene for widows peak?
sweeden
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.
In humans widows peak w is dominant over straight hairline w if a heterozygous male marries a female with a straight hairline what percent of their children can be expected to have a widows peak?
According to Mendelian genetics, if the male is heterozygous for the widows peak trait (Ww) and the female has a straight hairline (ww), 50% of their children are expected to have a widows peak (Ww) and the remaining 50% of their children are expected to have a straight hairline (ww).
What can be dominant or recessive?
Alleles can be dominant or recessive
What is the duration of Widows' Peak?
The duration of Widows' Peak is 1.68 hours.
Could 2 people with a widows peak have a child with a straight hairline and could 2 people with a straight hairline have a child with a widows peak EXPLAIN?
Yes to the first one, no to the second one. Firstly, widow's peak is caused by a dominant gene while a straight hairline is caused by a recessive gene. Let 'H' be dominant and 'h' be recessive. So for a dominant gene, the trait still will be expressed whether the genotype of the person is homozygous dominant(HH) or heterozygous(Hh). For a recessive gene however, the trait will only be expressed when the genotype of the person is homozygous recessive (hh). So two people with a widow's peak CAN have a child with a stright hairline, provided both of their genotypes are Hh. This is because by crossing their genotypes, they can have a possibility of having child with the genotype HH(widow's peak), Hh(widow's peak), and also hh(straight hairline). The ratio of these three possibilities however, are 1:2:1. So the odds of having a child with a straight hairline in this case is 1:3. If the two people who have widow's peak have the genotype HH or one of them HH and the other Hh, then the possibility of having a child with a straight hairline is 0. This is because by crossing their genotypes together, the genotype of the child will either be HH for the first case, and HH or Hh for the second case. For two people who have a straight hairline, the genotype of both will definitely be homozygous recessive (hh), thus child will definitely have the recessive gene. Therefore, it is not possible for two people with straight hairline to have a child with widow's peak.
