Is it true that people who are heterozygous recessive allele but who have a normal phenotype eill not pass the harmful recessive allele to their kids?
It depends on the genotype of the childs other parent. If your partner is heterozygous as well then there is a 25% chance your child will be homozygous recessive. If they are homozygous dominant then none of your children will have the phenotype of the recessive trait. They will just possibly be carriers of the recessive allele.
A male who has normal vision marries a female who is a carrier for colorblindness can they have a colorblind daughter?
Assuming that the man who has normal vision is homozygous for normal vision, the couple's daughter will either be homozygous for normal vision or heterozygous (normal vision but carrier for color blindness) for normal vision. In light of this, the couple's daughter will not be color blind.
What is two dominant alleles called?
In eyes, it would be brown is dominant, and blue is recessive. Free earlobe allele is said to be dominant over the attached earlobe allele. When an organism has two dominant alleles for a trait, it is called homozygous dominant. Two recessive alleles for a trait is homozygous recessive.
In the Hardy Weinberg equation shown below P is the frequency of the dominant allele and q is the recessive allele?
Homozygous recessive genotype
What is genotype of the plant with colored seed and normal strach you used in the test cross?
Homozygous recessive; if 'r' stands for color of the seed and 's' for normal starch, then the genotype of this plant used in a test cross will be ( rrss ).
What is an example of recessive human trait?
1. freckles: dominant no freckles: recessive 2. dark eyes: dominant light eyes: recessive 3. free earlobe:dominant attached earlbe: recessive 4. polydactilism (6 fingers or toes): dominant 5 fingers or toes: recessive 5. normal chin: recessivecleft chin: dominant 6. can roll tongue: dominant cannot roll tongue: recessive 7. cannot fold tongue: dominant can roll tongue: recessive 8. straight pinkie: dominant crooked pinkie: recessive 9. widow's peak: dominant straight hairline: recessive 10. separate eyebrows: dominant uni-brow: recessive
What would be the color vision of children if their mom is colorblind and their dad is normal?
Colorblindness is a recessive, sex-linked trait, and the gene that causes it occurs on the X chromosome. For the mother to be colorblind, she must have two copies of the gene and be homozygous recessive. The father, on the other hand, can not have the gene, because he (as a male) only has one X chromosome. So, if we let Xc represent the recessive gene for colorblindness and Xn represent the normal gene, the the mother is XcXc and the father is XnY. All of their children will receive the recessive gene from their mother. In the males, this means that they will be colorblind, because the chromosome they get from their father will by the Y chromosome. The daughters, however, will get the Xn gene, which is dominant and will override the gene for colorblindness. Thus, all of the couple's sons will be colorblind, and none of their daughters will be.
Can give example about overdominance?
Overdominance is when the heterozygote has an advantage over both the recessive and dominant homozygotes. Sickle cell disease is an example of this. When the individual is homozygous for the sickle cell allele, sickle cell disease is shown. When the the individual is homozygous for the wildtype allele, they appear normal. However, when the individual is heterozygous, he or she appears normal and will also be resistent to malaria.
What is the child's genotype if parents both have normal arches produce a child with flat feet?
Child's genotype would be homozygous recessive alleles (nn) and parents would both have heterozygous dominant alleles (Nn).
Can a individual carry a gene that is not expressed?
not usually, most books fit into the normal genres: mystery, fiction, nonfiction, adventure etc. I believe this person is referring to "genes," not "genres." To answer the question, then: yes, you can have genes that are not expressed. Recessive genes, for example, will not be expressed in heterozygous individuals; they will only be expressed in homozygous recessive individuals. For example; if you have the genotype Aa, the recessive gene - "a" - will not be expressed because the genotype contains a dominant allele, and the dominant allele will always be the one expressed. The only way that the "a" allele will be expressed is, again, if you are homozygous for that recessive gene (your genotype would be aa).
What is the difference between homozgous and heterozygous?
Heterozygous vs. Homozygous: These terms refer to genetic mutations. There are two copies of the protein codes in the genetic code. If one copy is normal and the other has the mutation, it is said to be heterozygous. If both copies have the mutation, it is said to be homozygous. For example: A/A -- homozygous. A/a -- heterozygous. a/A -- heterozygous. a/a -- homozygous.Homologous refers to the pair of chromosomes that are the same whilst Homozygous refers to the fact that alleles of a gene pair are the same
What is the genotype for sickle cell anemia?
homozygous recessive (rr) & Heterozygous (Rr) homozygous recessive (rr) & Heterozygous (Rr)
