Upon self-fertilization of Aa with itself, the probability of A gamete fusing A and a gamete is equal.Ĭlarification: The probability of occurrence of A and a is equal each has a chance of 50%. Hence Vv heterozygous plant would produce 50% V and 50% v containing gametes.Ħ. Thus the gametes will have 50% of each allele. What gametes are produced by a Vv heterozygous plant?Ĭlarification: The process of segregation that occurs during meiosis is a random process. This can be used to determine the genotypic and phenotypic ratios of the progeny.ĥ. What is represented in the boxes of the Punnett square?Ĭlarification: In the Punnett square, the boxes are filled with the offsprings that can be produced, in principle, from the combinations of gametes of both parents.
The gametes from the parents are represented on the top and the left sides of the Punnett square.Ĥ. Where are the parental genotypes mentioned in a Punnett square?Ĭlarification: Punnett square gives a graphical representation for the transfer of genetic information in crosses. Its importance was recognized by Gregor Mendel, who used it to study the patterns of inheritance and thus formulate the laws of inheritance.ģ. Who deserves the credit to discover Punnett square?Ĭlarification: The Punnett square was discovered by a British scientist named Reginald Punnett. Mendel employed it to study the genotypes of F1 and F2 progeny based on the games produced by the previous generation.Ģ. What diagram is used to study the production of zygotes in F1 and F2 generation?Ĭlarification: The Punnett square is a mathematical tool used in probability and statistics.
