Assume color in salamander follows simple dominance and recessive patterns. A green salamander of unknown genotype pairs with a white homozygous recessive salamander (gg). What are the two possible genotypes of the green salamander?


Well class, today we will be discussing the genetic cross between a green salamander of unknown genotype (which we will label as Gg) and a white homozygous recessive salamander (which we will label as gg). This cross can result in two possible genotypes for the green salamander offspring: Gg or gg. Now, when we want to visualize all the possible combinations of alleles that can result from a genetic cross between two parents, we use something called a Punnett Square. This diagram was first developed by Reginald C. Punnett in 1905 and is used to determine the probability of an offspring having a particular genotype. In terms of genotypes, there are three types: homozygous recessive, homozygous dominant, and heterozygous. And if a trait tends to be passed directly from parent to child, then it is likely a dominant trait. Conversely, if a trait skips generations, it is likely a recessive trait. It is important to note that a recessive gene only decides the appearance of an organism when it is present with another identical gene. If you want to learn more about the Punnett square, I invite you to refer to this helpful resource on brainly.com under the question ID #3522181 #SPJ13.
