In codominance, the involved alleles are equally expressed. Heter0zyg0us individuals express both phenotypes. Option A: 0% Silver, 50% Black, 50% Blak-lace.

Codominance refers to a non-mendelian inheritance pattern in which two alleles of the same are equally expressed. There is no dominant or recessive alleles, since non of them hides the expression of the other one in heter0zyg0us individuals.

The phenotype of a heter0zyg0te expresses two alternative variants inherited from each h0m0zyg0us parent.

When two individuals that are h0m0zyg0us and different for a trait are crossed they produce heter0zyg0us individuals.

These heter0zyg0us individuals express both parental phenotypes, as it is an additive expression of their parents' genes.

In the case of angelfish, their color is determined by codominance.

Genotype        Phenotype

LL                         Silver

BB                        Black

LB                        Black-lace

F1) 1/2 = 50% of the progeny is expected to be h0m0zyg0us BB, expressing the black phenotype

     1/2 = 50% of the progeny is expected to be heter0zyg0us Bb, expressing the black-lace phenotype

Option A is the correct table:

Explanation:

Since the Pitx1 gene codes for a protein crucial im lower limns development, a mutation occurring near Pitx1 gene will affect refikjs around the lower limbs but not those far away from it.

Mutations refers to alterations or error that occur which change the original sequence of nucleotides in a DNA molecule.

The Pitx1 gene is a gene that codes for a protein that involved in development of the lower limbs.

A mutation near but outside of the coding region of Pitx1 may cause a loss of pelvic fins without pleiotropic effects on the pituitary gland and jaw because the pelvic fins form part of the lower limbs whole the jaws and the pituitary gland are not found in the lower limbs.

Therefore, the mutation occurring near Pitx1 gene will affect regions around the lower limbs but not those far away from it.

Anything over or below the 1,013.25 mbar level, which is the mark used to indicate standard air pressure, is referred to as high air pressure.

The quantity of force exerted per square centimeter at a right angle to an object's surface is known as pressure. Its identifier is "p" as well as P. The IUPAC suggests using a lower-case p when referring to pressure. Nonetheless, many people use the capital P.

1. The portions of the chart in the middle and the lower left, or the 989 and 993 designated pressures with white hue, in addition to their surroundings down to the 1,012 mark, are the low pressure zones.

2. the region down to the 1,012 mark in the vicinity of the 995 marking in the upper half of the chart.

3. From the marker at 1005 in the lower right corner of the map to the marker at 1,012 around it.

Therefore, anything over or below the 1,013.25 mbar level, which is the mark used to indicate standard air pressure, is referred to as high air pressure.

The option that describes a benefit of sustainable agriculture is ; ( D ) soil erosion is reduced

Soil erosion is the gradual removal of soil particles which leads to the washing away of soil nutrients. soil erosion is caused by the negative impact of floods ( water and wind ).

The reduction in soil erosion is a benefit of sustainable agriculture. While The depletion of aquifers and the overgrazing of farmland are not benefits of sustainable agriculture.

Hence we can conclude that a benefit of sustainable agriculture is soil erosion is reduced.

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
