What determines whether a person is right or left-handed?
Handedness, or whether a person is right or left-handed, is determined by the dominant hemisphere of the brain. The dominant hemisphere controls the side of the body that is more skilled and coordinated, leading to a person being either right-handed or left-handed.
What happens to the recessive allele in a heterozygous offspring?
In a heterozygous offspring, the recessive allele is present, but it is overridden by the dominant allele in terms of physical expression. The recessive allele still remains in the genetic makeup of the offspring and can be passed on to future generations.
An example of a heterozygous recessive genotype is?
An example of a heterozygous recessive genotype is when an individual carries one dominant allele and one recessive allele for a particular trait. One example could be a person with the genotype Aa, where "A" represents the dominant allele and "a" represents the recessive allele.
A person with a heterozygous gene?
A person with a heterozygous gene has one dominant allele, usually represented by a capital letter, and a recessive allele, which is usually represented with a lowercase letter. So an example of a heterozygous gene would be Rr
What is a person with one recessive allele and one dominant allell for a trait called?
Heterozygous.
What is a person who has a dominant and one recessive copy of a disease gene?
A person who has one dominant and one recessive copy of a disease gene is typically considered to be affected by the condition if the disease is caused by the dominant allele. In this case, the dominant allele's effects will manifest, overshadowing the recessive allele. The individual may not express traits associated with the recessive allele, as the dominant trait takes precedence.
How does a person inherit hemophilia and is it dominant or recessive?
It is a sex-linked recessive trait inherited from the mother.
What determines whether a person is right or left-handed?
Handedness, or whether a person is right or left-handed, is determined by the dominant hemisphere of the brain. The dominant hemisphere controls the side of the body that is more skilled and coordinated, leading to a person being either right-handed or left-handed.
Which one of the following statements would most clearly refer to a person's genotype a susan has blue eyes b bill is recessive for height and dominant for hair c Karen has broad shoulds?
Statement B, "Bill is recessive for height and dominant for hair," most clearly refers to a person's genotype. This statement indicates specific genetic traits (height and hair type) and whether the traits are dominant or recessive in the individual.
What is the difference between dominant alleles and recessive alleles?
dominant-appears in first generation recessive-seems to dissapear
What is a person who has one recessive allele for a trait and one dominant allele for the same trait and is able to pass in the trait on to their offspring?
That is heterozygous. Some scientist call these "hybrids"(no joke)The person is heterozygous for that trait and will have the dominant phenotype.An organism with both a dominant and recessive allele for a specific trait is called an heterozygote. They are heterozygous for this trait.
Why are two recessive alleles needed for a recesssive trait to be shown?
bcoz in case of one dominant and one recessive, dominant allele will express its characters and suppresses the recessive ones. so for the expression of recessive characters both allele should be recessive.
Why is it that a person with an allele for a particular trait may not have a phenotype that shows the trait?
a dominant allele will express its trait , as well as be carried by the person. the word carrier is commonly used for a person who bears an allele which does not express itself(i.e. a recessive gene).
What happens to the recessive allele in a heterozygous offspring?
In a heterozygous offspring, the recessive allele is present, but it is overridden by the dominant allele in terms of physical expression. The recessive allele still remains in the genetic makeup of the offspring and can be passed on to future generations.
What is ti called a person with one recessive and one dominant allele for a trait?
inferior
What do you call a person who has one dominant and one recessive copy of a gene?
We call a gene that has two different alleles heterozygous.
Why cant you determine if a person with a dominant trait has the genotype true breeding dominant or hybrid simply looking at them?
Because the dominant traits cover up the recessive.
