Chromosome number varies from one organism to another. or example, humans have 46 chromosomes while bacteria have only one chromosome.
The problem associated with the chromosome number of various organisms faced by evolutionists is that with the decrease in the size of an organism, the number of chromosomes also decrease. Thus, it becomes difficult to find and study the chromosomes.
The branching point on a cladogram represents a common ancestor. A cladogram is a diagram used in cladistics to show relations among organisms. However it is not an evolutionary tree since it does not show how ancestors are related to descendants, nor does it show how much they have changed.
Offspring will be heterozygous expressing the dominant trait.
Hope this helps.
Answer:
Cas9
