Typically higher than a clear night
Answer:
long are W which means that they are stronger than the w trait of short.
1)the big word means that it will have two W traits, (or W,W), and heterozygous will mean that the seal will have one W and one w, (or W, w).
your Punnett Square will look like this W W which means that 100% of
these W W W W W
seals w W w W w
will have long.
2)Heterozygous and a short will look like this
w W w w w
w w w w w
which means that only 25% will have long and 75% will have short, this is due to how W traits will almost always beat recessive traits.
3)Now one is, (H) and two is, (h). Two Hybrid means that they are Heterozygous. This will make your Punnett Square look like this
H h
H H H H h
h H h h h
the possible Genotypes willbe H H, H h, h h.
Phenotypes, looktraits willbe One,and Two.
The bark of a tree is impervious to gases and water because bark cells are dead cells of the epidermis and compactly arranged without intercellular spaces. They contain a chemical called suberin in their walls that make them impervious to gases and water and it doesn't allow gases or water into the tree as bark cells are in the bark outer most layer of the tree.
Answer:
Mechanical isolation
Explanation:
mechanical isolation is a form of prezygotic reproductive barrier, whereby similar species organisms become isolated and unable to successfully interbreed with each other to form zygote, as a result of incompatibility of their reproductive organ or structure, which prevents them from copulating. As a result of this, both species become separated as there is no gene flow between both.
The two species of juniper can be said to be kept separate by <em>mechanical isolation</em>, due to the differences and incompatibility of their reproductive structure.
