Ans. B. Hox genes.

Hox genes (homeobox genes) can be defined as a group of related genes, which specify regions of an body plan of an organism's embryo along its head-tail axis. Given figure represents body plan in fruit fly, in which has eight Hox genes, clustered into two complexes.

These genes include labial (for head involution),  proboscipedia (for labial abd maxillary pulps), deformed (maxillary and mandibular segments), sex combs reduced (for cephalic and thoracic development), antennapedia (pair of legs and wings), ultrabithorax (pair of legs halteres), abdominal-A and abdominal-B (for abdomen).

Thus, the correct answer is option (B).

Distinguish between directional, stabilizing, and disruptive selection. Give examples.
pashok25 [27]
Directional selection is a type of natural selection that favors one extreme phenotype over the mean or another extreme. Examples of directional selection include giraffes that have long necks and the darkening of London's peppered moths after the Industrial Revolution.

Stabilizing selection, also known as purifying selection, is a type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value. An example of stabilizing selection is birth weigh in humans.

Disruptive selection is a type of natural selection that shows a preference toward the reproduction of genetic material at the extremes within a population.One of the most studied examples of disruptive selection is the case of ​London's peppered moths.

_____is an interaction between species that affects both species negatively (-/-), as they utilize similar resources.
jolli1 [7]

An interaction between species that affects both species negatively (-/-) , as they utilize similar resources is called as Competition .

Competition :

Competition is a process in which the fitness of individual of one species is significantly lower than that of the individual of same or different species.

Types of competition :

For the necessities of life , it is divided into two types .they are as follows,

A) interspecific competition : it is a competition which occurs between the individuals of two different species having some requirements of life , e.g.,carnivorous animals such as tiger ,lion ,leopard etc .compete for the prey . in the forest habitat ,herbs and trees compete for sunlight , water space , minerals , and biological pollinators .

If the individuals of two different species have sme one or more requirement the the competition becomes very severe e.g., grassland is the common habitat for bison ,dear rabbits ,rats grasshoppers , etc .if thee is short supply of grass due to draught then the competition becomes severe

The survival of the consumers is determined by the quantity of grass required by each species ,ability to change the food and its capacity to migrate to new localities.

B) Intraspecific competition : it occurs between the individuals of the same species .this type of competition is very severe as all the individuals of the same species have almost common requirement of food ,habit etc .besides they also exhibits similar adaptations to fulfill their requirements ,e.g., animals of same species compete for water ,food and mates .

Intraspecific competition is the driving force behind evolution and natural selection .

Thus the Competition only negative impact on environment.
