PLZ HELP I WILL MEDAL AND FAN! Describe the Punnett Square, and how it shows possible offspring outcomes using key words from your genetics unit. Be sure to discuss the parents' and offsprings' genetic make-up. Below is a list of recommended key terms. * Gene, Allele, Dominant, Recessive, Homozygous (dominant or recessive), Heterozygous, Genotype, Phenotype
The Punnett square is a diagram that is used to predict an outcome 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 allele's with paternal allele. [1] These tables can be used to examine the genotypic outcome probabilities of the offspring of a single trait (allele), or when crossing multiple traits from the parents. The Punnett Square is a visual representation of Mendelian inheritance. It is important to understand the terms "heterozygous", "homozygous", "double heterozygote" (or homozygote), "dominant allele" and "recessive allele" when using the Punnet square method. For multiple traits, using the "forked-line method" is typically much easier than the Punnett square. Phenotypes may be assessed using a Punnet square, but the phenotype that may "appear" from a given genotype can rely on many things that you will learn about in further detail as you advance through Genetics. -- Wikipedia ( http://en.wikipedia.org/wiki/Punnett_square)
I was asking for a description of the punnett square that is shown in the link but thx any way :)
