A dihybrid cross tracks 2 genetic traits from 2 parents.
First you need to look at all the potential combinations of each parent
Parent 1: heterozygous tall & heterozygous round Tt & Rr
Parent 2: Homozygous dominant tall & wrinkled TT & rr
(use something like foil and look at all the possible options)
Parent 1: TR , tR, Tr, or tr
Parent 2: Tr
TR . tR . Tr tr
Tr . TT Rr . Tt Rr . TT rr Tt rr
Results show that 50% of offspring will be Tall & Round and 50% will be tall and wrinkled (phenotype)
however genotype displays a 1:1:1:1 ratio as none of the genotypes are exactly the same
Alfred Wegner intitally theorized that the continents may have been joined at once, because their landforms were similar and almost fit as puzzle pieces. As well as finding the same fossils.
Answer:
Well, Earth is the same way! Earth is made up of several different layers, each of which has unique properties. Both parts of the core are made up of mostly iron and some nickel. The difference is that in the inner core, those minerals are solid and in the outer core, they're liquid.
In codons and acids its simple some amino acid don't link to codons so there are specific codon and amino acid links that will work most wont though codons have a specific link to one amino acid
that would be my answer hope it helps :)
The Ferrel cell is the middle cell, one of the three cells in each hemisphere in which air circulates through the entire depth of the troposphere. This cell occurs between 60 and 70 degrees north and south and <span> the surface wind flows from a southerly direction in the northern hemisphere. From the given options, in a Ferrel cell a Westerlies can occur. </span>
