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.

I changed it- does it look okay now? AndyZ 01:43, 16 February 2006 (UTC)[reply]

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[reply]

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)[reply]

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)[reply]

Tone

[edit]

The tone of the sections on Mendel's experiments seems rather unencyclopedic. --Khajidha (talk) 11:49, 4 April 2019 (UTC)[reply]
