In a pedigree where curly hair (C) is a dominant trait, the genotypes of the parents can vary. If at least one parent has curly hair, their genotype could be either CC (homozygous dominant) or Cc (heterozygous). If both parents have straight hair (which is the recessive trait), their genotype must be cc. To determine the specific genotypes of the parents more accurately, you would need to analyze the phenotypes of their offspring in the pedigree.
curly hair, as the dominant gene overrules the recessive gene I THINK :)
i think its doinant
All of their children will have straight hair, as the father can only pass on the dominant straight hair allele. The children will inherit one straight hair allele from their father and one curly hair allele from their mother, but the dominant straight hair allele will mask the recessive curly hair allele.
If we cross a homozygous dominant fruit fly with straight wings (WW) and a homozygous recessive fruit fly with curly wings (ww), all offspring in the first generation (F1) will be heterozygous (Ww) and exhibit straight wings. If we then cross two F1 flies (Ww x Ww), the second generation (F2) will show a phenotypic ratio of 3 straight-winged flies to 1 curly-winged fly, resulting in about 75% straight wings and 25% curly wings.
When talking about cells, there's a DOMINANT trait and a RESSECIVE trait. The DOMINANT is obviously... well, the dominant one. And if you're writing out the traits, the DOMINANT receives a capital letter and the RESSECIVE receives a lowercase letter, which will sometimes be cursive. I hope that helps! =)
No, curly hair is dominant
Dark hair (black or brown) are considered to be dominant genetic traits over lighter colors like blonde and red. This is a very simplified perspective of the genetics of hair color. Hair color is coded by multiple genes, so this is slightly more complex in reality.
it is because the parents each were heterozyous dominant. meaning each of them had a dominant allele and a recessive allele. the dominant allele would be the curly hair, and the recessive allele would be the straight hair. There would be a 1/4 chance that the child would have curly hair, and a 3/4 chance that they would have curly hair. Say that the Curly hair allele was H and the straight hair allele was h. In order for the parents to have curly hair, they would either have to have an HH gamete or an Hh gamete. Seeing as though the child came out with curley hair, both parents would have to have an Hh gamete. In order to find out the probability, you multiply the parents gametes. (Hh)(Hh). This will give you HH, Hh, Hh, hh. seeing has three of the gametes have the dominant allele, this child will have curly hair, and one is a homozygous recessive, so it will turn out with straight hair.

it depends on which allele is most dominant in the parents.
Yes.
Dominant.
Yes! It's more likely that the child would have straight hair, but it's all about the genes. Likely both of the straight-haired people have straight-hair dominant genes; if that's true, then there's about a 25% chance that the child would have curly hair. If the parents or even grandparents had curly hair when they were younger, it's more likely as well. For example -- both of my parents have straight hair (but my mom had curly hair when she was younger) and my sister has straight hair as well. I turned out to have curly hair.
The LaPerm cats have a dominant gene that make them have curly hair.

If you have straight hair of curly hair. I think straight haris is dominant.
