<span>The crossed flies are heterozygous so they have one allele of each for the characteristics. So the genotype is Bb for body color and Rr for eye color.
To set up the punnett square, you would determine all possible combinations for the alleles that each parent could provide: BR, Br, bR, and br. Then make the table, and combining the rows and columns:
BR Br bR br
BR BBRR BBRr BbRR BbRr
Br BBRr BBrr BbRr Bbrr
bR BbRR BbRr bbRR bbRr
br BbRr Bbrr bbRr bbrr
There are sixteen combinations of the genotypes and they need to be classified: BB or Bb- Brown body; bb- black body; RR or Rr- red eyes; rr- brown eyes
Brown body and red eyes- 9
Brown body and brown eyes- 3
Black body and red eyes- 3
Black body and brown eyes 1</span>
The reasons why a rancher may plant several varieties of grass for grazing on the same ranch are for making hay where some horse owners may prefer to feed their animals with a feeding mixture of alfafa hay and timothy hay. Secondly, they plant the grasses for grazing their animals since the grasses may be having different soil conditions in different fields. lastly, the farmers may be raising different animals with varying nutritional needs.
Proteins are macromolecules that are made up of the subunits that are called amino acids, there are 20 fundamental kinds of amino acids present. These varying combinations of them make different proteins needed for numerous functions.
