Is chromosomal mutation dominant or recessive?

They can be both. Wikipedia provides small descriptions of some of the different types of mutation


Using the terms dominant recessive explain the difference between genotype and phenotype?

No, I think you have your terms confused.The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what alleles an organism has for a particular locus. The two alleles (in most cases) inherited (one from mother and one from father) can either be dominant or recessive. The recessive allele is not fully expressed in the presence of the dominant allele and is only expressed when there are two recessive alleles. The genotype could be called "recessive" I suppose if the genotype is homozygous recessive. But remember that two recessive alleles as a genotype is only one possibility - in which case you can't say the "genotype is recessive".The phenotype is dependent on the genotype. If present, the dominant alleles (in simple Mendelian genetics) will determine the phenotype - what the organism's trait or characteristic is. The phenotype will never be what is coded by the recessive allele unless the genotype is two recessive alleles.


What genotype is homozygous?

Total dominant genes or total recessive genes. Therefore, either TT or tt, not Tt.


Is a gender a dominant or recessive gean?

Purebreds can be recessive or dominant, depending on their genotype. A genotype for spots on a griaffe could be AA (purebred dominant), Aa (heterozygous dominant), or AA (purebred recessive)? AA and Aa would both show the dominant phenotype, but only AA and AA are purebreds.


What must the genotype of an X-linked recessive trait be for a woman to express it?

If the woman does not show the trait, she must have a dominant allele (version of the gene); let's call it A. She also carries the recessive gene, a. So her genotype is Aa. This means that half her ova (gametes) will contain the dominant A, half a.The rest is up to the sperms; half of them will carry an X chromosome, with either A or a on it (unless there are more than two alleles involved).

An example of a heterozygous recessive genotype is?

You can't have heterozygous dominant or recessive. A genotype is either homozygous dominant (MM), homozygous recessive (mm) or heterozygous (Mm). Hope it helps!


What genotype is homozygous?

Total dominant genes or total recessive genes. Therefore, either TT or tt, not Tt.


What following genotypes will express a dominant trait?

For a dominant trait to be expressed, you either need a RR or an Rr genotype. The other genotype, rr, is recessive only. In genetics, capital letters represent a dominant allele, and lower case letters represent the recessive allele.


What is an individual with genotype AAA described as?

An Aa genotype can result in the same phenotype as either an AA or AA genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.

How many offspring are likely to have recessive traits if the parents are hybrids?

50%. There are four possible outcomes of the cross:dominant trait from "dad", dominant trait from "mom"recessive trait from "dad", dominant trait from "mom"dominant trait from "dad", recessive trait from "mom"recessive trait from "dad", recessive trait from "mom"Therefore, to get hybrid offspring (one dominant, one recessive), you have a 2 out of 4 chance.


What are the different forms of a gene either dominant or recessive?

heterozygous, homozygous dominant or homozygous recessive


An allele is either what or what?

Dominant or recessive


Is it possible to determine the genotype of a plant with a dominant phenotype the trait?

NO, because a dominant phenotype could either be homozygous or a heterozygous.so unless you are sure about the genotype of parents we can't determine it...but we can determine the genotype of a person showing reccessive phenotype, as a recessive trait always expresses itself in a homozygous condition..Read more: Is_it_possible_to_determine_the_genotype_of_a_person_showing_a_dominant_phenotype


What is example of a genotype?

There are genotypes and phenotypes discussed in genetics.Genotypes include both recessive and dominant genes, and is the genetic makeup of the organism.Phenotypes are only the traits that are observed in an organism, i.e. double-recessive, or dominant genes.If you looked at horned/polled(no horns) cattle. The polled gene is dominant, the horned gene is recessive.A cow with horns would be expressing the horned phenotype. It would also have the double-polled genotype since it is a recessive gene.A cow without horns would be expressing the polled phenotype. However, it could have either 2 polled genes for the genotype, or it could have 1 polled gene and 1 horned gene for the genotype.
