Fungi and bacteria are primary decomposers whereas plants and trees are producers and animals are consumers
I'm pretty sure that it's C. I'm not quite sure though.
Chitin - part of insects hard body and part of fungus
Cellulose - part of plant cell walls
Pectin - also part of plant cell walls
Answer:
The three genes in coupling are in repulsion.
Explanation:
Coupling happens when the dominant alleles and the recessive alleles are on the same homologous chromosome, while the repulsion happens when one chromosome has one dominant allele and one recessive allele and another homologous chromosome also has dominant and recessive alleles.
If the progeny has:
nb+ ls+ a/nb ls a ⇒ nb+ ls+ a
nb ls a+/nb ls a ⇒ nb ls a+
Where nb+ ls+ a is the dominant alleles and nb and nb+ is in middle.
ls+ nb+ are on the same chromosome (both dominant)
ls nb are on the same chromosome (both recessive)
ls nb, these two are in coupling with each other, but ls+ and a are on the chromosome and ls+ or nb+ are dominant, while nb+ and a are recessive on form a, thus, ls and nb, they are in repulsion with a.
1/4. Make a Punnett square and plug in the two heterozygous genotypes of the parents, put them together and you get the following possible genotypes: AA, Aa, Aa, and aa. One of those is homozygous dominant. 1/4 or 25 percent.
