Most mutations in eukaryotes exhibit a recessive inheritance pattern because they typically involve changes in a single gene, and the presence of a normal copy of the gene can often mask the effects of the mutated gene. This means that individuals with one normal and one mutated copy of the gene will not show the effects of the mutation, leading to a recessive inheritance pattern.

What are the inheritance patterns for each plant type?
Inheritance patterns for plants can vary depending on the type of plant. In general, plants can exhibit different patterns of inheritance such as dominant, recessive, codominant, or incomplete dominance. These patterns determine how traits are passed down from one generation to the next.
How is inheritance different from dominant recessive inheritance?
Dominance is when one gene completely takes over the phenotype, and codominance is when two genes are equally expressed. For example: Dominance: Red flower x yellow flower = red flower (red gene is expressed, but yellow gene isn't) Codominance: Red flower x white flower = flower with red petals and white petals (both the red gene and the white gene are expressed)
Will an organism with a recessive allele for a particular form of a trait will always exhibit that form?
No, an organism with a recessive allele for a particular trait will only exhibit that form if it has two copies of the recessive allele (homozygous recessive). If it has one dominant allele, it will exhibit the dominant form of the trait.
What type of inheritance pattern (are the A and B alleles to each other (Autosomal dominant-Regular dominant-recessive relationship, X linked, co-dominant, incomplete dominant)?
Incomplete dominance
Which trait will a male exhibit if he carries a recessive allele on the X chromosome?
A male carrying a recessive allele on the X chromosome will exhibit the recessive trait. This is because the Y chromosome generally does not have matching genes for the X chromosome, unlike the other 22 pairs if chromosomes in the nucleus.

What gene will exhibit its traits even in a prensesce of a recessive gene?
A dominant gene will exhibit its traits even in the presence of a recessive gene. This is because the dominant gene masks the expression of the recessive gene when present in the same individual.
Will an organism with a recessive allele for a particular form of a trait will always exhibit that form?
No, an organism with a recessive allele for a particular trait will only exhibit that form if it has two copies of the recessive allele (homozygous recessive). If it has one dominant allele, it will exhibit the dominant form of the trait.
Which types of muscular dystrophy are autosomal recessive diseases?
Some forms of LGMD and DD exhibit this pattern of inheritance, as does CMD. A person with only one flawed copy, called a carrier, will not have the disease, but may pass the flawed gene on to his children.

Incomplete dominance

What genotype is ff?
The genotype ff represents a homozygous recessive individual for a specific gene. This means that both alleles for the gene are the same and both are the recessive allele (f). This individual will exhibit the trait associated with the recessive allele.
What is A herterozygous individual who has one allele for a disease but is not affected by it?
A heterozygous individual who has one allele for a disease but is not affected by it is considered a carrier. Carriers can pass the disease allele to their offspring but do not exhibit the symptoms themselves. This is common in genetic disorders that follow a recessive inheritance pattern.
Is the following sentence true or false all genes show simple patterns of dominant and recessive alleles?
False. Blood type genes have two dominant alleles (A and B), and one recessive (O). When a person gets one A allele and one B allele, they then have the blood type AB. Both are expressed equally. In other genes, a dominant allele might not be completely dominant, allowing the recessive allele to be partially expressed.
ABO blood groups exhibit what type of inheritance pattern?

What is the phenotypic ratio of the following dihybrid cross AaBb x AaBb?
The phenotypic ratio of the cross AaBb x AaBb is 9:3:3:1, which represents the different possible combinations of genotypes for the offspring based on the principles of Mendelian genetics. This ratio indicates that 9 out of 16 offspring will exhibit the dominant phenotype for both traits, while 3 out of 16 will exhibit one dominant and one recessive phenotype, 3 out of 16 will exhibit the other dominant and recessive phenotype, and 1 out of 16 will exhibit both recessive phenotypes.
