Completely unclear
[edit]A monohybrid cross, in genetics, is the inheritance of a single pair of contrasted characteristics.
A monohybrid cross is not an inheritance.

Figure should be corrected
[edit]Allele names in figure 1 are not standard - Rw should be changed to Ww (or Rr), then the punnet square could use the same letters. How does one edit a picture on here? Dr d12 18:44, 2 December 2006 (UTC)Dr_d12
This has not been cleared up and it is definitely a poor diagram to use for this entry. The text uses the simple "Bb" mode of denoting alleles, but the diagram does not. In addition, the text refers to a different diagram than the one shown, I think.Soupyx (talk) 11:49, 13 September 2008 (UTC)
Inconsistent Definition
[edit]The article states that:
"A monohybrid cross is a cross between parents who are heterozygous at one locus.
and then the following example is given which contradicts this definition:
"For example, a monohybrid cross between two pure-breeding plants (homozygous for their respective traits)..."
Incorrect information
[edit]The information in the second and third sentences of the monohybrid cross page is incorrect.
The sentences currently at the page state: "A monohybrid cross is a cross between parents who are true-breeding for a trait; i.e., both are homozygous for one allele of the gene, for example AA x aa, in which A is the dominant allele for a trait and a is the recessive allele for that same trait. The cross between their offspring is referred to as a dihybrid cross, in which parents are both heterozygous at one locus."
Suggested correction: A monohybrid cross is a cross between two hybrid or heterozygous organisms; i.e., both are heterozygous or carry two different alleles of the gene, for example Aa X Aa, in which A is the dominant allele for a trait and a is the recessive allele for that same trait.
The other sentence is also wrong. A dihybrid cross is a cross between two organisms who are heterozygous at two loci, for example AaBb X AaBb, in which A is the dominant allele for a trait and a is the recessive allele for that same trait and B is the dominant allele for a second trait and b is the recessive allele for the second trait.

Introduction
[edit]This could really do with a paragraph or two in something approaching plain English (or at least the language of high school level science). --Oolong (talk) 07:22, 18 October 2013 (UTC)
Tone
[edit]The tone of the sections on Mendel's experiments seems rather unencyclopedic. --Khajidha (talk) 11:49, 4 April 2019 (UTC)
