Biogeographic isolation means that a population is separated and there are two populations in two different areas. As normal mutations take place, but certain mutations will be seen as advantageous in the different areas. For. Example if an area had taller trees the organism may develop a gene to grow taller. This is then passed down to offspring. This process continues so that more gene differences are created within the species and the frequency of these alleles increased: leading to two different species developing-
A plant cuticle is a protecting film covering the epiderms of leaves, young shoots and other other aerial plant organs with out periderm. It consists of lipid and hydrocarbon polymers impregnated with was and is synthesized exclusively by the epidermal cells.
Answer:
The given blank can be filled with location of gene expression.
Explanation:
A regulatory sequence refers to a section of a molecule of nucleic acid that possesses the tendency of declining or upsurging the expression of particular genes within an organism. The regulation of gene expression is an important characteristic of all living species and viruses.
In the given case, it is essential to use the regulatory sequence of a milk gene when developing a recombinant gene as a regulatory sequence monitors the location of gene expression.
Answer:
0%
Explanation:
Round = Dominant
Wrinkled = recessive
Recessive = r
Dominant = R
homozygous dominant = RR
homozygous recessive = rr
Heterozygous= Rr
Since both seeds are homozygous recessive (rr)
In your punnet square, one lower case r will go on the top and the left side
r r
r
r
Something like that.
Go across your four boxes and you will end up with;
rr, rr
rr, rr
In order for it to be round, at least one box would need to have to be a heterozygous(Rr) or be a homozygous dominant.
