Talk:Monohybrid cross

Completely unclear

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)

Figure should be corrected

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

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

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

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

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