Complete the punnett square for the following cross-pollination and give the genotypic and phenotypic ratios: for white (ww) and black (ww) female: x male: ww male: ww

Punnett Squares are used to demonstrate the genotypic and phenotypic ratio of a certain trait in an organism. The cross between the traits can be monohybrid, dihybrid, or trihybrid.

In the given cross, the WW stands for white, whereas ww stands for black.

The cross between the heterozygous white female (Ww) with the black male (ww) is given in the attachment below.

Thus, the ratio is 1:1.

To know more about Punnett square, refer to the following link;

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: blah

explanation:

bc blah

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
