Final answer:
Without specific traits, it's not possible to evaluate genotypes or calculate probabilities. Survival in the natural habitat depends on traits and their advantageous or detrimental effects. Traits that aren't present in parents can show up in offspring through recessive alleles.
Step-by-step explanation:
The question refers to a fictional species called a unicorn. Without specific traits provided, it is not possible to evaluate the possible genotypes for traits 1, 2, and 3 or calculate the probabilities for inheritance. However, in general, Punnett squares can be used to calculate the expected proportions of genotypes and phenotypes in a monohybrid cross. Traits that aren't present in either parent can show up in the offspring or future generations due to the presence of recessive alleles.
Regarding the species' survival in its natural habitat, it would depend on the specific traits and their effect on the unicorn's ability to adapt and thrive. If certain genotypes are advantageous for survival, they may increase the species' fitness, while others may be detrimental. It would require a detailed analysis of the specific traits and their interactions with the environment to assess the impact on the species' survival.
