Is the white tigers fur mutation dominant or benificial?
Well, the white tigers fur mutation isn't dominant nor beneficial (depends). The allele for white fur in tigers is recessive and even then not many tigers are heterozygous (One dominant allele and one recessive allele for those who do not know) Now it can be beneficial depending where the tigers live, there used to be Siberian Tigers who lived in the snow so it would be beneficial there but white fur will decrease stealth ability in the jungles, therefore alleles can be beneficial or harmful depending on the allele and where the organism lives.
Can a white offspring be a hybrid why?
If the white trait is dominant, then yes. If the white trait is recessive, then no.
What happens when an allele is dominate or recessive?
Well, a dominant allele carries dominant traits from parents to offspring. An example of a dominant trait is brown hair and brown eyes because these traits are most likely to show up on a human than a recessive allele. A recessive allele may carry a recessive trait from parents to offspring such as blonde hair and blue eyes, these are uncommon because they are recessive traits.
What kind of trait is expressed when two different genes from the same trait are present?
It depends on the gene in question, and the type of dominance of the trait.For monogenetic traits (those controlled by a single gene), the dominant trait(s) will be expressed when two different alleles are present.For example, if B leads to black fur and b leads to white fur:Complete dominance would result in a rabbit with Bb having black fur.Incomplete dominance - Bb would result in grey furCodominance - Bb would result in black and white patches/spots/etc.
What is the difference between dominant and recessive alleles for specific traits?
Dominant is an allele that will always be expressed in a heterozygous individual. Recessive on other hand are traits that will only be expressed in a homozygous condition. Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.
If a homozygous dominant is crossed with a homozygous recessive for a given trait the offspring will be?
The phenotype will show the dominant trait. All dominant traits mask recessive ones; If the genotype is heterozygous (One dominant and one recessive) the organism's phenotype will be dominant.
A cross between homozygous purple-flowered and homozygous white-flowered pea plants results in offspring with purple flowers This demonstrates?
A homozygous purple flower and a homozygous white flower having offspring that are purple is an example of dominance. Traits that yield to other traits is referred to as recessive. So in this case Purple was the dominant trait and White was the recessive trait.
What is the kind of trait that seemed to vanish in the offspring produces in Mendel's first experiment?
Mendel's experiments showed the characteristics of genes that express complete dominance--that is, traits where one allele is completely dominant over another, and the recessive allele does not appear in the phenotype at all. Some of the specific traits that Mendel was testing include pea color (yellow or green, with green being completely dominant) pea surface texture (wrinkled or smooth, with smooth being dominant) and flower color (pink and white, with pink being dominant.)
What is the difference between dominant alleles and recessive alleles?
dominant-appears in first generation recessive-seems to dissapear
Is codominance recessive or dominant?
Codominance is not the same as recessive or dominant. If two alleles are codominant, both traits are expressed in the phenotype (i.e. they both show in the organism). For instance, if a cow inherits genes for both red (R) and white(W) hairs, it will have the genotype RW, and some of its hairs will be red and some white, giving it a coat called roan.
How many white tigers in the world?
White tigers are born in only one in 10,000 births of Bengal tigers. It is a recessive gene variation.
What is the intermediate form that led to white tigers?
There is no intermediate form that led to white tigers. White tigers are simply Bengal tigers with a white coat. The white coat is caused by a recessive gene. Bengal tigers are the only subspecies with the recessive gene. Both parents must have the recessive gene, although, both parents can themselves be orange coated. It is the same as humans that have blue eyes. Brown eyed parents can have blue eyed children, but both parents must have the blue eyed recessive gene.
