  2. Punnett square - Wikipedia

    en.wikipedia.org/wiki/Punnett_square

    The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. [9] These tables can be used to examine the genotypical outcome probabilities of the offspring of a single trait (allele), or when crossing multiple traits from the parents.

  3. Reginald Punnett - Wikipedia

    en.wikipedia.org/wiki/Reginald_Punnett

    Reginald Punnett was born in 1875 in the town of Tonbridge in Kent, England. While recovering from a childhood bout of appendicitis, Punnett became acquainted with Jardine's Naturalist's Library and developed an interest in natural history. Punnett was educated at Clifton College. [6]

  4. Test cross - Wikipedia

    en.wikipedia.org/wiki/Test_cross

    Punnett squares showing typical test crosses and the two potential outcomes. The individual in question may either be heterozygous, in which half the offspring would be heterozygous and half would be homozygous recessive, or homozygous dominant, in which all the offspring would be heterozygous.

  5. Hereditary carrier - Wikipedia

    en.wikipedia.org/wiki/Hereditary_carrier

    Punnett square: If the other parent does not have the recessive genetic disposition, it does not appear in the phenotype of the children, but on the average 50% of them become carriers. A hereditary carrier ( genetic carrier or just carrier ), is a person or other organism that has inherited a recessive allele for a genetic trait or mutation ...

  6. Phenotype - Wikipedia

    en.wikipedia.org/wiki/Phenotype

    Here the relation between genotype and phenotype is illustrated, using a Punnett square, for the character of petal color in pea plants. The letters B and b represent genes for color, and the pictures show the resultant phenotypes. This shows how multiple genotypes (BB and Bb) may yield the same phenotype (purple petals).

  7. Mendelian inheritance - Wikipedia

    en.wikipedia.org/wiki/Mendelian_inheritance

    Each has one allele for purple and one allele for white. In the offspring, in the F 2-plants in the Punnett-square, three combinations are possible. The genotypic ratio is 1 BB : 2 Bb : 1 bb. But the phenotypic ratio of plants with purple blossoms to those with white blossoms is 3 : 1 due to the dominance of the allele for purple.
