When one gene can compensate for the loss of function of another gene The phenomenon is called?

When one gene can compensate for the loss of function of another gene The phenomenon is called?

Glossary.

Term Definition
genetic compensation changes in RNA or protein levels that can functionally compensate for the loss of function of another gene
transcriptional adaptation changes in RNA levels that result from a genetic mutation and not from the loss of gene function

What is the genotype of a female who is heterozygous for eye color?

BB
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb.

What is true of genes for two different traits that are located next to each other on the same chromosome?

The closer two genes were to one another on a chromosome, the greater their chance of being inherited together. In contrast, genes located farther away from one another on the same chromosome were more likely to be separated during recombination.

Which of these facts if he had known them might have led Mendel to formulate different rules for inheritance?

Which of these facts, if he had known them, might have led Mendel to formulate different rules for inheritance? There are many genes on each chromosome. Consider a disease allele that is both dominant and lethal to patients that possess it. How could such an allele be passed on from generation to generation?

When a single gene exhibits multiple phenotypic expression?

Pleiotropy (from Greek πλείων pleion, ‘more’, and τρόπος tropos, ‘way’) occurs when one gene influences two or more seemingly unrelated phenotypic traits. Such a gene that exhibits multiple phenotypic expression is called a pleiotropic gene.

What occurs when a single gene affects more than one trait?

How can a mutation in one single gene cause a disease with a wide range of symptoms? This situation is referred to as pleiotropy, and it has been identified in a wide range of species, even humans.

How do you know if you are heterozygous or homozygous?

Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent. They do not match.

What are gene maps based on?

​Genetic Map The map is based on the idea of linkage, which means that the closer two genes are to each other on the chromosome, the greater the probability that they will be inherited together. By following inheritance patterns, the relative locations of genes along the chromosome are established.

How did Mendel find out whether the recessive alleles were still present in the F1 plants?

How did Mendel find out whether the recessive alleles were still present in the F1 plants? He allowed the F1 plants to produce an F2 generation by self-pollination. 13. About one fourth of the F2 plants from Mendel’s F1 crosses showed the trait controlled by the allele.

What are the two situations in which independent assortment of genes occur resulting in 50\% recombination?

Two situations are: (i) When the genes of different traits are located on the same chromosome and must be distantly located to enhance the recombination frequency. (ii) When the genes of different traits may be located on different chromosomes.

How many peas are produced when two different genes are crossed?

Two heterozygous pea plants for two different genes are crossed. One gene codes for seed color, where yellow (Y) is dominant over green (y). The other codes for seed texture, where round (R) is dominant over wrinkled (r). 1) 192 peas are produced.

What happens when two different alleles are present in the same gene?

In true breeding strains, both alleles are the same for a gene. Since there is only one kind of allele present, mating two plants from the same strain will produce offspring that have the same phenotype and genotype as their parents. Plants or animals with two identical alleles for a gene are said to be homozygous.

How many alleles do children inherit from their parents?

Children inherit two alleles for each gene from their parents, one from the mother and one from the father. The genotype refers to which two alleles an organism has. Sometimes both alleles are the same and sometimes they are different.

How do you determine the genotype of a plant with red flowers?

At the end of your biology class, your professor asks you to develop a project to determine the genotype of a plant with red flowers. Red petal color (R) is dominant to pink flower color (r). To accomplish this task, you cross the plant with the unknown genotype with heterozygous red-flower (Rr) plants.
