The genes involved in pattern formation and organization of body parts are called homeobox genes, which are a large family of similar genes.

The h<span>omeobox genes direct the formation of many body structures during early development of the embryo. </span>

The genes that are involved in pattern formation and organization of body parts are called MASTER DEVELOPMENTAL REGULATORY GENES. Master developmental regulatory genes control development. These genes encode transcription factors and cell signalling molecules. <span />

7) 4 unique haploid daughter cells are formed:

Anettt [7]

Answer:

Meiosis II

Telophase II

Explanation:

The chromosomes line up in a similar way to the metaphase stage of mitosis. The sister chromatids separate and move toward opposite ends of the cell. Meiosis II results in four haploid (N) daughter cells. You have FOUR (4) daughter cells with the haploid number (N) of chromosomes

No they cant be mechanical because then something would have to generate their rays through the inventing of a machine.

Consider the data on cliff swallow mortality. Why is this an example of directional selection?Overall genetic variation decrease

Gala2k [10]

Answer:

The average trait value changed in one direction.(In this case, larger size)

Explanation:

In evolution a natural selection can be disruptive, directional or stabilizing

In stabilizing no extreme trait is favored hence provides intermediate values .

Disruptive selection both extreme traits are favored over the intermediate trait.

Directional, the enviroment will favor the survival of one trait hence a change in direction either towards the left or the right.

In the case of swallow cliff mortality, selection favored the larger size.

Whats the difference between genotype and phenotype.

Olegator [25]

$\huge{\green}\fcolorbox{blue}{cyan}{\bf{\underline{\red{\color{red}Answer}}}}$

The genotype is a set of genes in the DNA which are responsible for the unique trait or characteristics.
Whereas the phenotype is the physical appearance or characteristic of the organism.
Thus, we can find the human genetic code with the help of their genotype.
Organisms may look the same but still may not have the same genotype.
One can determine the genotype by the biological tests.
On the other hand, the phenotype is determined by an individual’s genotype and can be expressed as genes or by the visible traits.
Such traits are hair color or type, eye color body shape, and height, and many such more.
It will depend on the genotype but also influenced by the factors existing in the surrounding.
