Monohybrid Crosses and Punnett Squares Punnett squares are diagrams that can be used to predict the offspring that could result from combination of the gametes produced by two parents (or an organism that can self-) The from the gametes of one parent (eg, eggs) are placed on one axis of the Punnett square while alleles from the gametes of the other parent (egsperm) are placed on the other 1. Pea plants have two alleles for height T is the dominant allele and produces tall plants recessive allele and produces short plantsConsider two parental pea plants each have the genot and answer the following questions aWhat type of gametes can a plant with genotype produce? bAssign the maternal gametes to one axis in the Punnett square at right Assign the paternal gametes to one axis in the Punnett square at night Copyright 2017 Pearson Education

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
