What is an example of a heterozygous chromosome?
An example of a heterozygous chromosome is having one chromosome with a dominant allele and the other with a recessive allele for a particular gene. This can lead to different traits expressed depending on the dominant or recessive nature of the alleles.
Chromosome that has both dominant and recessive gene?
A chromosome can have both dominant and recessive genes for a specific trait, but only one gene will be expressed in an individual. The dominant gene will be expressed over the recessive gene in a heterozygous individual. This is known as the principle of dominance in genetics.
Can a sex-linked allele be dominant?
Yes, a sex-linked allele can be dominant. For example, if a gene on the X chromosome is dominant, females who inherit the allele will express the trait, while males only need one copy of the dominant allele to show the trait since they have only one X chromosome.
Which chromosome Klinefleter's Syndrome affect?
Klinefelter Syndrome is neither recessive or dominant. It is a chormosome disorder, and is thus not passed down from generation to generation. The disorder is a random even that occurs.
What sex chromosome is donated by the mother?
The mother typically donates an X sex chromosome to her offspring. This is because females have two X chromosomes, and during reproduction, one of these X chromosomes is passed on to the offspring, determining the sex.
What is an example of a heterozygous chromosome?
An example of a heterozygous chromosome is having one chromosome with a dominant allele and the other with a recessive allele for a particular gene. This can lead to different traits expressed depending on the dominant or recessive nature of the alleles.
What is dominant the X or the Y?
An allele on either X or Y could be dominant over the allele on the other chromosome, but it is more common for the allele on the X to be dominant, because the Y chromosome is much smaller than the X and contains fewer genes. In many cases, there is no allele for a particular gene on the Y chromosome; so whatever allele is on the Y will be dominant.
Is hunters disease dominant or recessive?
Hunter's disease is inherited in an X-linked recessive pattern. This means the mutated gene that causes the disease is located on the X chromosome, and males are more commonly affected because they only have one X chromosome. Females can carry the mutated gene but are typically unaffected due to having a second X chromosome that can compensate.
Chromosome that has both dominant and recessive gene?
A chromosome can have both dominant and recessive genes for a specific trait, but only one gene will be expressed in an individual. The dominant gene will be expressed over the recessive gene in a heterozygous individual. This is known as the principle of dominance in genetics.
Is the extra copy of Chromosome 21 that causes Down syndrome dominant or recessive?
Down syndrome is neither caused by dominant or recessive chromosomes it is simply caused by an error in the translation process of chromosome 21.
Can a sex-linked allele be dominant?
Yes, a sex-linked allele can be dominant. For example, if a gene on the X chromosome is dominant, females who inherit the allele will express the trait, while males only need one copy of the dominant allele to show the trait since they have only one X chromosome.
Is hemophilia caused by a dominant allele on the x chromosome true or false?
false
What genes are expressed even when present on only one chromosome?
dominant genes
What chromosome is associated with patau syndrome?
nondisjunction
Is Down syndrome a dominant or recessive?
Down syndrome is neither dominant nor recessive. Actually, it is considered to be an "autosomal" trait. This occurs when there is damage to the chromosome.
Why are traits controlled by recessive alleles on the X chromosomes are more common in males then in females?
In males, they only have one X chromosome, so if they inherit a recessive allele for a certain trait on their X chromosome, it will be expressed because there is no corresponding dominant allele on the Y chromosome to mask it. Females have two X chromosomes, so even if they inherit a recessive allele on one X chromosome, the dominant allele on the other X chromosome can mask its expression.
Which chromosome Klinefleter's Syndrome affect?
Klinefelter Syndrome is neither recessive or dominant. It is a chormosome disorder, and is thus not passed down from generation to generation. The disorder is a random even that occurs.
