[Answer] A plant can produce either purple flowers or white flowers. What is the probability of purple-flowered offspring if two plants that are heterozygous for purple flowers are crossed?

Mendelian inheritance is a type of biological inheritance that follows the principles originally proposed by Gregor Mendel in 1865 and 1866 re-discovered in 1900 and popularized by William Bateson. These principles were initially controversial. When Mendel’s theories were integrated with the Boveri–Sutton chromosome theory of inheritance by Thomas Hunt Morgan in 1915 they became the core …

Mon Mar 15 2004 13:30:00 GMT-0500 (Eastern Standard Time) · The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.The Punnett square is a tabular summary of possible combinations of maternal …

For example in co-dominance a red homozygous flower and a white homozygous flower will produce offspring that have red and white spots. When plants of the F1 generation are self-pollinated the phenotypic and genotypic ratio of the F2 generation will be 1:2:1 (Red:Spotted: White ). These ratios are the same as those for incomplete dominance.

A monohybrid cross is a cross between two organisms with different variations at one genetic chromosome of interest. The character(s) being studied in a monohybrid cross ar…
