Answer:

a)Lophotrochozoam

  • Many free living things larvae
  • Several groups has lophophore
  • Nearly all animals are sessile adults

b)Ecdyozoams

  • Phyla where the organisms molt their outer layer for growth.

in mendelian genetic , allele of each genes from the parents will segregate from each other so the gametes only carry one each.

If the parental mice has two different fur color (i.e white and Black) , the color of the offspring's fur would be either black, white, or the combination of both (Grey)

hope it helps

In messenger RNA, each codon calls for a
olganol [36]

Answer: c) amino acid

Explanation: A codon is an mRNA sequence which contains three nucleotides that codes for a particular amino acid. The codons on the mRNA are read by the ribosome during translation and the amino acid coded for by each codon is used to make a protein. There are 64 different codons in existence, each amino acid is coded for by at least one codon. Some amino acids have more than one codon. For example, the amino acid Leucine is coded for by six codons: UUA, UUG, CUU, CUC, CUA and CUG while the amino acid phenylalanine is coded for by two codons: UUU and UUC.

The number of possible genetically different gametes for an organism equals
masya89 [10]

The organism can produce 12 genetically different gametes.

<h3><u>Explanation:</u></h3>

The gametes are the unit of sexual reproduction which are produced by an organism from their germ mother cell by means of meiosis. This gametes do carry half the amount of total chromosomes that is present inside each cell of that organism. This process let's the genetic combinations of chromosomes to get more variations among offsprings. But this isn't the only source of variation among the offsprings.

Each and every germ mother cell that's undergoing the meiotic division undergoes a process called crossing over and chaismata formation which gives the genetic mixing among the different alleles of same character among the organism.

Thus, statistically, if the organism has n pairs of chromosomes, then the organism will be able to produce 2n number of genetically different gametes which helps in finding out the probability of genotype of the offsprings.

So if the organism has 6 pairs of chromosomes, then the organism will be able to produce 12 genetically different gametes.
