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
Answer: information max
Explanation: As a cell increases in size, it usually does not make extra copies of DNA. If a sell became too large, an “information max” would occur. The cell has more trouble moving enough nutrients and waste across the cell membrane.
The one in my opinion that best describes a leaf is tissue. it can't be the organism because that would be the tree itself. In a like fashion, it can't be the organ because the branches of the tree would be the organs. Since the leaves make up the branches... they would be tissues.
Symbiotic bacteria have already established their colonies in the host hence prevent the invasion of other bacteria through competition. They act as a barrier to keep nastier pathogens at bay. These bacteria are also important in mucosal immunology of humans by influencing on the development and function of both innate and adaptive branches of the immune system.
