Study Notes
Principles of Inheritance: An In-Exploration of Punnett squares
Inheritance is the process by which traits are passed on from parents to their offspring, and it is the basis of heredity. Genes, the basic unit of inheritance, are located on chromosomes, and they are the means by which traits are inherited. Variation exists among individuals of one species due to factors including crossing over, recombination, mutation, and environmental effects on the expression of genes
Mendel's Laws of Inheritance:
- Law of Dominance: In a dihybrid cross, the phenotype of the heterozygote (the individual with two different alleles for a gene) is determined by the dominant allele
- Law of Recessive: In a dihybrid cross, the phenotype of the heterozygote is determined by the dominant allele, and the allele that is not dominant (reessive) is not manifested
- Law of Inheritance: In a dihybrid cross, the phenotype of the offspring is determined by the alleles inherited from both parents
Mendel's Laws of Inheritance can be visualized using Punnett squares, which are a way to predict the potential combinations of offspring from two parents of known genotype
Incomplete Dominance:
Incomplete dominance is a type of inheritance pattern in which the heterozygote expresses intermediate or a mixture of two parents' traits
Incomplete Dominance can be visualized using Punnett squares, which illustrate the different combinations of alleles that can result in the heterozygote's phenotype
Incomplete Dominance is an example of a deviation from Mendel's Laws of Inheritance, and it is a way to understand how genes and their alleles are passed down from one generation to
