If a blue-eyed man marries a brown-eyed woman whose mother was blue-eyed dominant what proportion of their children will have blue eyes?
- A male X-linked trait has only one allele. This is because they have one Y chromosome and one X chromosome. Females have two X chromosomes. Y chromosomes do not have alleles. Thus, the father must have had only one blue eye recessive allele. This means that 100% of the children will have brown eyes, unless there is, like above, something that goes awry from the typical biological rules. So this means that the original person was not correct. If you think I am wrong, just do a Mendel's Square.
- Genetic scientists are studying why some children have brown, green or blue eyes (some amber) when they have parents who have their own individual eye color. Genetic scientists highly consider the fact that millions of years ago all humans had brown eyes, but because of genetics this has changed. Since it is extremely complicated and involves DNA here is a link that can better describe the color of the human eye and how it is determined: http://www.thetech.org/genetics/ask.php?id=29

The genotype of the unaffected children is?
The genotype of the unaffected children can be 1 of 2 different things. The genotype can be either completely dominant or heterogeneous.
Which characteristic is more frequently dominant in Paleolithic sculptures of women?
ability to produce children
If Tall is dominant over short a homozygous dominant man marries a homozygous recessive woman what of their children are expected to be short?
All of their children are expected to be heterozygous for the trait (Tt), which means they would be tall (dominant phenotype). The recessive trait for being short would only manifest if both copies of the gene were recessive.
How large are dominant elements?
Dominant elements, which refer to the most abundant species in a given environment or ecosystem, can vary significantly in size depending on the context. In ecology, they might range from large trees in a forest to small herbaceous plants in a grassland. In terms of chemistry, dominant elements in the Earth's crust, like oxygen and silicon, constitute a large proportion of the planet’s composition but are not measured in physical size. Thus, the size of dominant elements is context-dependent, based on the specific field of study.
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.
What proportion of WwRr will be dominant in both traits?
9/16
In a dominant characteristic a man who does not have a chin dimple has children with a woman with a chin dimple. What proportion of their children would be expected to have a chin dimple?
50% would be expected to have the dimple, but in the pot shoot that makes up our genetic material, all or none may in reality end up dimpled.
Would you expect there to be more children with the dominant phenotype or recessive phenotypewhy?
There would likely be more children with the dominant phenotype because it only requires one copy of the dominant allele to express the dominant trait, whereas the recessive phenotype requires two copies of the recessive allele.
What language is dominant in the western hemisphere?
The dominant language in the western hemisphere is Spanish. It is spoken by a large proportion of the population in most countries in North, Central, and South America, as well as in parts of the Caribbean.
Should parent have children if they have dominant defective gene?
Yes
Is a female colorblinded trait dominant?
It is dominant. Most likely if the female had children then all her sons would be color blind. If she herself was also color blind then all her children would be color blind too.
Who is more dominant a female jaguar or a male jaguar?
Male jaguars are generally more dominant in the animal kingdom. However, when it comes to the female jaguar protecting her children, the female can become pretty aggressive and controlling/dominant.
The genotype of the unaffected children is?
The genotype of the unaffected children can be 1 of 2 different things. The genotype can be either completely dominant or heterogeneous.
How can you use dominant trait in a sentence?
The dominant trait for eye color in humans is brown, which means that if one parent has brown eyes and the other has blue eyes, the child is more likely to inherit brown eyes due to the dominant trait.
Which characteristic is more frequently dominant in Paleolithic sculptures of women?

If Tall is dominant over short a homozygous dominant man marries a homozygous recessive woman what of their children are expected to be short?
All of their children are expected to be heterozygous for the trait (Tt), which means they would be tall (dominant phenotype). The recessive trait for being short would only manifest if both copies of the gene were recessive.
Are dimples a recessive or dominant trait?
Dimples are thought to be a dominant trait, meaning that an individual only needs one copy of the gene for dimples to have them. If both parents have dimples, their children are likely to inherit dimples as well.
