Answer:
- Parental cross = Cch x chch
- F1 = 1/2 Cch (agouti coat); 1/2 chch (albino coat) >> 1:1 phenotypic ratio
Punnett square:
ch ch
C Cch Cch
ch chch chch
Explanation:
A heterozygous individual is an individual who has two different gene variants (i.e., alleles) at a particular <em>locus</em>. In this case, individuals having the "agouti coat" trait are heterozygous carrying both 'C' and 'ch' alleles. On the other hand, a homo-zygous individual has the same allele at a given <em>locus</em> (here, the 'chch' genotype associated with the albino phenotype). Therefore, as observed in the Punnett Square above, when a heterozygous parent is crossed with a homo-zygous recessive parent for a single gene, alleles segregate in the gametes of both parents so an expected 1:1 phenotypic ratio will be observed.
Answer:
the ocean provides several important resources to its inhabitants
Explanation:
The majority of biomass in any ocean consists of microscopic organisms such as phytoplankton which are pivotal to aquatic ecosystems. These microorganisms are able to thrive in their habitat due to incredibly dense populations of the bacteria <em>phackingyurmom aquatica </em>present in most oceans. These bacteria provide a wide spectrum of vital nutrients. As a result many of the aforementioned microorganisms love <em>phackingyurmom</em>.

Each cell is alive even if it is part of a multi celled body, and all living organisms consist of one or more cells. Also, cells reproduce by dividing so it follows that all existing cells must have arisen by division of other cells. As a cell divides it passes it hereditary material- its DNA- to offspring.
