What is Mendelian genetics? Answer must include dominance and recessiveness.
Genetic analysis predates Gregor Mendel, but Mendel's laws form the theoretical basis of our understanding of the genetics of inheritance. Mendel made two innovations to the science of genetics: 1. developed pure lines 2. [ counted his results and kept statistical notes Dominant - the allele that expresses itself at the expense of an alternate allele; the phenotype that is expressed
in the F1 generation from the cross of two pure lines Recessive - an allele whose expression is suppressed in the presence of a dominant allele; the phenotype that disappears in the F1 generation from the cross of two pure lines and reappears in the F2 generation ]

What is Mendelian genetics? Answer must include dominance and recessiveness.
Weegy: Mendelian inheritance (or Mendelian genetics or Mendelism) is a set of primary tenets relating to the transmission of hereditary characteristics from parent organisms to their children; it underlies much of genetics A Mendelian trait is one that is [ controlled by a single locus and shows a simple Mendelian inheritance pattern. In such cases, a mutation in a single gene can cause a disease that is inherited according to Mendel's laws In genetics, dominance describes the effects of the different versions of a particular gene on the phenotype of an organism. Many animals (including humans) and plants have two copies of each gene in their genome, one inherited from each parent. The different variants of a specific gene (such as that coding for earlobes) are known as alleles. If an organism inherits two alleles that are at odds with one another, and the phenotype of the organism is determined completely by one of the alleles, then that allele is said to be dominant. The other allele, which has no tangible effect on the organism's phenotype, is said to be recessive. Sex linkage is the phenotypic expression of an allele that is related to the chromosomal sex of the individual. This mode of inheritance is in contrast to the inheritance of traits on autosomal chromosomes, where both sexes have the same probability of expressing the trait. Since, in humans, there are many more genes on the X than there are on the Y, there are many more X-linked traits than there are Y-linked traits. In mammals, the female is the homogametic sex, having two X chromosomes (XX), while the male is heterogametic, having one X and one Y chromosome (XY). Genes that are present on the X or Y chromosome are called sex linked genes. Source(s): Wikepedia:) Sex cell of a plant or animal may contain one factor (allele) for different traits but not both factors needed to express the traits. Characteristics are inherited independently from other characteristics. Each inherited ... (More)
