What is a monohybrid cross?

A monohybrid cross is a genetic cross between two individuals that differ in only one trait or in one gene locus. This type of cross helps to study the inheritance patterns of a single trait and can provide insights into how genes are passed down from parents to offspring. By analyzing the offspring of a monohybrid cross, geneticists can determine the dominant and recessive alleles involved in the trait and predict the probability of certain traits appearing in future generations.

Who is considered the "father of genetics"?

Gregor Mendel is considered the "father of genetics" for his pioneering work on the inheritance of traits in pea plants, which laid the foundation for the science of genetics. Through his experiments, Mendel discovered the basic principles of heredity, including the concepts of dominant and recessive traits, which revolutionized our understanding of how traits are passed down from generation to generation.

What is the Law of Segregation?

The Law of Segregation, proposed by Gregor Mendel, states that each individual has two alleles for each gene and when gametes (sperm and egg cells) are formed, these alleles separate so that each gamete carries only one allele for each gene. This means that offspring inherit one allele from each parent, leading to genetic diversity in populations.

What is a genotype?

A genotype refers to the genetic makeup of an organism, which consists of the specific combination of alleles for a particular trait. This genetic information is inherited from the organism's parents and influences the physical characteristics and traits that an individual will have.

What is a phenotype?

A phenotype is the observable characteristics of an organism resulting from its genetic makeup and the interaction with its environment. It encompasses traits such as physical appearance, behavior, and physiological functions that are expressed by an individual.

What is the difference between homozygous and heterozygous genotypes?

Homozygous genotypes have two identical alleles for a particular gene, while heterozygous genotypes have two different alleles for the gene. This means that homozygous individuals can either have two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive), whereas heterozygous individuals have one dominant and one recessive allele.

What is the Punnett square used for in monohybrid crosses?

The Punnett square is a tool used in genetics to predict the outcome of a monohybrid cross, which involves following the inheritance of one specific trait from two parents. By organizing the possible genetic combinations of alleles from the parents into a grid, the Punnett square allows us to determine the probability of certain traits being expressed in the offspring.

How do you calculate the probability of a specific genotype or phenotype in a monohybrid cross?

To calculate the probability of a specific genotype or phenotype in a monohybrid cross, you can use the Punnett square method. First, determine the genotypes of the parent organisms and write them on the sides of the square. Then, fill in the squares with the possible combinations of alleles to determine the genotypes of the offspring. Finally, calculate the ratio of each genotype or phenotype to find the probability. Remember to consider the principles of Mendelian genetics, such as dominant and recessive alleles, when assigning probabilities to each outcome.

What is the difference between dominant and recessive alleles?

Dominant alleles are expressed phenotypically when present with a recessive allele, while recessive alleles are only expressed phenotypically when two copies are present. Dominant alleles mask the presence of recessive alleles in a heterozygous individual, displaying their phenotype instead.

Can you give an example of a monohybrid cross and explain the resulting phenotypic ratios?

Sure, a classic example of a monohybrid cross is the mating of two pea plants that differ in just one trait, such as flower color. Let's say we cross a homozygous purple-flowered plant (PP) with a homozygous white-flowered plant (pp). The resulting phenotypic ratio will be 100% of the offspring having purple flowers (Pp genotype), as purple is dominant over white in pea plants. Therefore, the phenotypic ratio of the offspring will be 1:0 for purple to white flowers.
