The kernel color in wheat is a continuous trait determined by two additive genes, each with two alleles, that equally contribute

Answer:

Phenotypic ratio: 1:4:6:4:1

Punnett square: Below in the explanation box

Frequency distribution: In the attached files

Explanation:

Available data:

The kernel color in wheat is a continuous trait determined by two additive diallelic genes
The red kernels are determined by two genes and two dominant alleles (R1R1R2R2)
The white kernels are determined by two recessive alleles at the same two genes (r1r1r2r2)
R1 and R2 alleles are dominant over r1 and r2, respectively

If a compound has a number of individual dipoles, then: I. It is polar overall. II. There is an electronegativity difference bet

Rudik [331]

Answer:

II. There is an electronegativity difference between the bonded atoms.

Explanation:

In a compound that has a number of individual dipoles(weaker force of attractions between compounds). There exist a weaker intermolecular force of attraction ( Vander waal's forces), these force of attraction arises from fluctuating dipoles in atom molecules brought by the movement of electrons around the atomic nucleus. They possess weak electronegativity difference between the bonded atoms because they have less energy to break these weaker bonds.

Also, individual dipoles can interact with each other in an way which will also increase the boiling point and as boiling point increases there is decrease in electronegativity difference between the bonded atoms.

On the other-hand, A polar compound are ionic compounds and the bonding between them are electrovalent bonding because of their high melting and boiling points. They possess high electronegativity.
