Answer:
Bioluminescence
Explanation:
Jellyfish have bioluminescent proteins. Bioluminescence is when a living organism gives off light through a chemical process. The glow you see is when a substance called luciferin reacts with oxygen.
C) Atoms nucleus.<span> The nucleus contains protons, that have positive charges, and neutrons.</span>
Answer:
Phenotypic ratio= 1:1
Genotypic ratio = 1:1
Explanation:
This is a monohybrid cross involving a single gene that specifies a color phenotype.
According to the question, WW, which is homozygous dominant i.e same allele is white while ww, which is homozygous recessive is black.
Hence a genotype Ww will possess a white phenotype since the W allele will mask the expression of w.
In a cross between a female and male with a a Genotype Ww and ww respectively. The parents alleles will be separated into gametes according to Mendel's law of segregation. (See attached image).
Ww will produce gametes W and w
ww will produce gametes w and w
The four possible offsprings will have Ww (2) and ww (2) genotypes. Hence two of them will be white while two will be black.
Hence, the phenotypic ratio will be 1:1 while the genotypic ratio will also be 1 Ww: 1 ww
