Principles of Genetics: Law of Dominance

According to the First Law of Inheritance, characters are controlled by continuous units called factors.

The Law of Dominance explains the expression of both parental characters in the F2 generation.

According to the Law of Segregation, alleles show blending in the F2 generation.

Homozygous parents produce gametes that are all different.

Incomplete dominance refers to when the F1 generation phenotype resembles one of the two parents.

Mendel's test cross involves crossing a homozygous individual with an unknown genotype with a homozygous recessive individual.

Pedigree analysis is a tool used in human genetics to trace the inheritance of traits over generations.

In pedigree analysis, inheritance of a specific trait is not represented in the family tree.

DNA carries genetic information and remains unchanged as it is passed from one generation to the next.

Mendel's test cross is used to determine the genotype of an individual with a dominant phenotype.

Mutation is a term used to describe changes or alterations in genetic material.

Genotypic ratios are not related to the study of phenotypic traits and inheritance patterns.

Individuals with Klinefelter's Syndrome have a karyotype of 47, XXY.

Individuals with Turner's Syndrome have a karyotype of 45 with XXY.

Mendel was the first biologist to systematically study the pattern of inheritance.

According to Mendel, factors regulating the characters are found in triplets known as alleles.

In the Punnett square, the offspring's genotypic ratios can be predicted based on the parents' genotypes.

Phenotypic traits are always determined solely by dominant alleles.
