What else can I help you with?
What will determine the genotype of an organism?
The alleles that are passed from parents to offspring
When can you accurately determine a person's genotype from their phenotype?
Yes you can accurately determine an organisms genotype by observing it's phenotype, however some phenotypic traits resulting from homozygous or heterozygous combinations of alleles, may make the prediction impossible.
What percentage of the F2 generation had the genotype tt?
In a typical monohybrid cross involving two heterozygous parents (Tt x Tt), the F2 generation would have a genotype ratio of 1:2:1 for TT, Tt, and tt respectively. This means that 25% of the F2 generation would have the genotype tt. Thus, the percentage of the F2 generation with the genotype tt is 25%.
Can you determine the genotype of a person just by looking at him or her?
No, the genotype of a person cannot be determined just by looking at them. Genotype refers to the genetic makeup of an individual, which is not visible. Physical appearance is determined by a combination of genetic and environmental factors.
If one parent has the genotype Cc for hair color and the other parent has the genotype cc what percentage of the offspring will have the recessive genotype for hair color?
50% of the offspring will have the recessive genotype (cc) for hair color when one parent is Cc and the other parent is cc. This is because all their children will inherit one "c" allele from the parent with cc genotype.
How can one determine the genotype of parents?
To determine the genotype of parents, one can perform a genetic test to analyze their DNA. This test can reveal the specific genetic variations or alleles that each parent carries, which can then be used to determine their genotype.
What percentage of possible types of offspring had genotype of the same genotype as the parent?
75 percent
What will determine the genotype of an organism?
The alleles that are passed from parents to offspring
Does phenotype determine genotype?
It is a false statement that "phenotype determines genotype". In fact, it is the opposite. A genotype is the genetics or "instructions" that determine the phenotype. The phenotype is the actual appearance, ex: blue eyes, that is created by a given genotype.
How can one determine whether a genotype is heterozygous or homozygous?
One can determine whether a genotype is heterozygous or homozygous by looking at the alleles present. If there are two different alleles for a particular gene, the genotype is heterozygous. If there are two of the same alleles, the genotype is homozygous.
Can you accurately determine an organisms genotype by observing it's phenotype?
No, genotype actually determines phenotype.
What is the important of test cross?
to determine the unknown genotype.
What is a testcross in biology?
a cross between an organism whose genotype for a certain trait is unknown and an organism that is homozygous recessive for that trait so the unknown genotype can be determined from that of the offspring
The mating of an individual of unknown genotype with one that is homozygous recessive in order to determine the unknown genotype is a?
Test Cross.
When can you accurately determine a person's genotype from their phenotype?
Yes you can accurately determine an organisms genotype by observing it's phenotype, however some phenotypic traits resulting from homozygous or heterozygous combinations of alleles, may make the prediction impossible.
What percentage of the F2 generation had the genotype tt?
In a typical monohybrid cross involving two heterozygous parents (Tt x Tt), the F2 generation would have a genotype ratio of 1:2:1 for TT, Tt, and tt respectively. This means that 25% of the F2 generation would have the genotype tt. Thus, the percentage of the F2 generation with the genotype tt is 25%.
Is phenotype determine genotype false?
Yes, this is false. It's genotype that determines phenotype. e.g. If you have the dominant gene for brown eyes and the recessive gene for blue eyes (genotype) you will have brown eyes (phenotype)
