The right answer is C

An allele is a variable version of the same gene, because a gene can have several versions of the same gene, which can give slightly different structural proteins due to these variations in the DNA, thus, giving different phenotypes.

In most cases, the multiplicity of alleles in a gene gives phenotypic variation in the population due to their different expression. Therefore, the larger the number of alleles, the greater the number of phenotypes in the population.

To a lesser extent (more rarely), some variation can be a deletion giving non-functional proteins, causing rare diseases (like cystic fibrosis, hemophilia, sickle cell anemia).

Bees see the colors yellow and blue, but not red. Flowers that need to be pollinated by bees are mostly yellow of blue. What typ

Inga [223]

Answer:

Natural Selection

Explanation:

In natural selection process of evolution, traits that are essential for an individual to be fit enough to survive under environmental stress become dominant.

Since the flowers are of blue or yellow color, it is essential for a bee to be able enough to perceive the blue and yellow color. Hence, the eyes of bee with time have evolved to perceive these two color so that they can pollinate flower.

A dihybrid cross is performed between plants that differ in two Mendelian traits: Stem length (T or t) and flower coloration (R

Dahasolnce [82]

Answer:

A. 3/16

Explanation:

The four possible outcomes for Stem length are:

Tt, tT, TT and tt.

The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.

The four possible outcomes for flower coloration are:

Rr, rR, RR and rr.

The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.

Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

$\frac{3}{4}*\frac{1}{4}=\frac{3}{16}$

Therefore, the answer is A. 3/16

The appropriate response is Iron-fortified breakfast cereal or little measures of lean meat. Invigorated sustenances are nourishments to which additional supplements have been included. Cases of these supplements incorporate vitamin A, B vitamins, vitamin D, folic corrosive, iodine, and iron. The first reason for nourishment stronghold was to diminish the event of supplement inadequacies.
