What else can I help you with?
What is the difference between a homozygous dominant homozygous recessive and heterozygous individual?
They are the same
Which genotype is used in a test cross?
In a test cross, one individual with a dominant phenotype but unknown genotype is crossed with a homozygous recessive individual. The genotype of the individual with the dominant phenotype can then be inferred based on the phenotypic ratios of the offspring.
When both alleles of genes are the same what is the individual?
homozygous
When both allele of the gene are the same what is the individual?
homozygous
What is having 2 sets of identical genes?
This individual is Homozygous.
Is the genotype of the individual homozygous or heterozygous for the trait in question?
The genotype of the individual is homozygous for the trait in question.
What is the probaility that the offspring of a homozygous dominant individual and a homozygous recessive individual will exhibit the dominant phenotype?
100 percent.
Are both alleles the same in a homozygous individual?
Yes, in a homozygous individual, both alleles for a particular gene are the same.
What is the difference between a homozygous dominant homozygous recessive and heterozygous individual?
They are the same
What is the percentage of offspring that will exhibit the dominant trait from A crossing of A homozygous dominant and homozygous recessive individual?
The homozygous dominant individual can only pass on the dominant allele and the homozygous recessive individual can only pass on the recessive allele, therefore all offspring will be heterozygous and have the dominant phenotype.
What term describes an individual with two copies of the same allele?
The individual with two of the same allele is "homozygous" for a trait.
An individual with two identical alleles of a gene is?
An organism that has two identical alleles for a trait is known as a homozygote or a homozygous organism.
Why can the father not be homozygous for a dominant trait?
Homozygousity is defined as having the two alleles that are the same for a certain locus. For example, AA or AA are both homozygous. Dominance, however, is a different concept and it is independent of homozygousity. In addition, both dominance and homozygousity are independent of the sex of the individual (unless the trait is X-linked) Therefore, the three possibilities of homozygous dominant, heterozygous, and homozygous recessive for a trait are available for a male just as a female individual.
Which genotype is used in a test cross?
In a test cross, one individual with a dominant phenotype but unknown genotype is crossed with a homozygous recessive individual. The genotype of the individual with the dominant phenotype can then be inferred based on the phenotypic ratios of the offspring.
What type of gene has Identical alleles?
A homozygous gene has identical alleles. Homozygous means the individual has two copies of the same allele for a particular gene.
When both alleles of genes are the same what is the individual?
homozygous
When both allele of the gene are the same what is the individual?
homozygous
