Are all mutations dominant?
Not all the time remember that in mutations it is a accidental change in the genetic code for example if you change one letter in a entire sentience you can change the message. the cat sat on the rug the car sat on the rug the cat sat in the rug
A genetic trait which is present but unseen in an individual is called a trait?
Recessive For example, brown eyes (B) are dominant, blue eyes (b) are recessive. BB = brown Bb = brown bb = blue In the Bb genotype, the blue eyed gene is present, but the brown eyed gene is dominant, and show as the phenotype
How do snowshoe hares and Arctic foxes camouflage?
Their coats change color to blend with the dominant color of the season- white in winter.
How would a baby change if one parent was homozygous dominant for all the traits and the other parent was heterozygous?
If one parent is homozygous dominant for all traits (carrying two dominant alleles for each trait), and the other parent is heterozygous (carrying one dominant and one recessive allele for each trait), there would be a 100% chance that the baby would inherit the dominant alleles from the homozygous dominant parent. Therefore, the baby would also be heterozygous for all the traits, carrying one dominant and one recessive allele for each trait.
Is Jacob's disease recessive or dominant?
i'm gonna have to say its recessive because it'm a mutation otherwise known as a change in the DNA sequence and it varies upon person because the sperm cell is the carrier of the yy gametes (sex cells) thus it varies upon parents.
What is the difference between genetic a disorder and a genetic mutation?
Mutation is any change in the genetic code of an individual regardless of how the change manifests. A genetic disorder is the result of an unfavorable mutation that results through through heterozygous recessive parents producing a homozygous recessive offspring, a random dominant mutation, or multiple polygenic mutations that compound for a negative effect on an individual as examples.
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
How does an Arctic hare change its environment?
Arctic hares do not change the environment, they adapt to it.
Can brown eyes change color?

Does natural selection cause a change in the gene frequencies of the population over time?
Recessive genes are replaced by dominant genes over time and unfavorable genes die out.
When offspring show a blend of the parents traits one allele is dominant over the other?
The results in the offspring hinge on the genetic make up of the parents. Each expressed trait is either the result of a dominant or recessive phenotype. The relative dominance or recessiveness of the alleles doesn't change only the rate at which they are expressed based on the allele present for each obseerved trait in the parents.
What evidence do scientists use to prove that evolution has occurred?
Simple example. You know hair color is under genetic control. Two types, blond ( which is recessive ) and brown ( which is dominant ) exist in our population. These two alleles are in a 75% to a 25% frequency. ( dominant to recessive ) if that frequency changed to 60% to 40% you could say that evolution had taken place. Evolution is the change in allele frequency in a population of organisms over time. ( example very simplified ) PS Scientist do not prove things. They support their work with the evidence.
