Here is a Punnett square <span> that shows a cross between a heterozygous red bull (Rr) and a heterozygous red cow (Rr).
Since the phenotype is unknown, we could say it's short ( RR) (Rr) and long (rr)
Since it's mixed, we could say that the ratio is 3/1</span>
Answer:
Isn't there any photo or some options at least? Actually, it says which of the following-that's why I asked
Explanation:
If you add something as a reference then I will be able to answer and help you :)
Meiosis produce variations in daughter cells whereas mitosis produce identical nuclei.
Hope this helps!
The answer would be 1. original-tissue fossils and 2. many species were wiped out
This was a hard one but I did some research and I found this
Our genome has 3 billion base pairs so a naive calculation shows 3x10^36 different combinations. But that's a meaningless number. A lot of those variants would be silent mutations, i.e. changes in introns, repeated sequences, 3rd position codons, etc etc that would have no effect on the phenotype.
Hope this help
