A tall sheep is crossed with a short sheep, and the progeny are all intermediate in size between the two parental sheep. This could be an example of ___________

When geneticists have an organism that displays the dominant trait but do not know the genotype, a test cross can be performed to help determine this.  A test cross is performed by mating a _________________ with the organism and looking at the physical traits of the offspring.

1. A purebred dog with brown fur and brown eyes is mated with a pure breed dog with white fur and blue eyes (note: this is hypothetical). All the F1 progeny are brown fur with brown eyes. Define your symbols __________________________________________________________________ a) What is the genotype of the F1 generation? _______________________ b) What are the resulting phenotypes of the F1 x F1 cross? __________________ Phenotypes:___________________________________________________________________________________________________________________________________________________

Can i please get help with the answer and please show me the work with an explaintion so I can understand
