D: needs to be present on both chromosomes to be expressed
Why: Because if there was a dominant trait present, then the dominant trait would overpower the recessive trait regardless of the matter.
Two limits to cell growth is by rates of protein synthesis and by the folding rates of its slowest protein
Overtime the ecosystem will start to decline...animals will start to die due to not having homes and the oxygen level in the environment will decline. It will be harder to live there and the sustainability will be low
So it will float on top of the water
An individual having two different alleles of a specific gene is described as being Heterozygous for that specific trait.
You have a heterozygous genotype for that gene if the two versions differ. Being heterozygous for hair color, for example, means you have one allele for red hair and one allele for brown hair. The interaction of the two alleles influences which traits are expressed.
Being homozygous for a gene means you inherited two identical copies. It is the inverse of a heterozygous genotype, in which the alleles differ. People with recessive characteristics, such as blue eyes or red hair, are always homozygous for that gene. In genetics, heterozygous means having inherited different versions (alleles) of a genomic marker from each biological parent. As a result, a person who is heterozygous for a genomic marker has two distinct versions of that marker.
