Where should the origin of jointed appendages be placed on the phylogenetic tree?

In the world of purple people eaters, one eye (E) and one horn (H) are dominant traits. Purple people eaters

Tju [1.3M]

Answer:

3

Explanation:

Male ; EeHh

Female ; EeHh

Then,

possible gametes for each = EH / Eh / eH / eh

where,

EH Eh eH eh

EH EEHH EEHh EeHH EeHh

One eye One eye One eye One eye

One horn One horn One horn One horn

Eh EEHh EEhh EeHh Eehh

One eye One eye One eye One eye

One horn Two horn One horn Two horn

eH EeHH EeHh eeHH eeHh

One eye One eye Two eye Two eye

One horn One horn One horn One horn

eh EeHh Eehh eeHh eehh

One eye  One eye  Two eye  Two eye 

One horn Two horn  One horn Two horn 

Therefore,

One eye, one horn:One eye, two horn:Two eye, one horn:Two eye,two horn

is,

9 : 3 : 3 : 1

This ration proves that the above working is correct and is dihybrid cross.

The more ________________ the homologous structure, the more likely they _______________ shared a common ancestor

Natali [406]

The more numbers of the homologous structure, the more likely they have recently shared a common ancestor.

Explanation:

Homologous organs are defined as those organs which do have different functions but a similar basic structure which denotes the divergent evolution. Homologous organs are seen in species that are very close to each other which are more related with each other in terms of evolution. For example, a bird is more close to each man than a fish, so do share more homologous organs common to man than fishes do. Examples of the homologous organs are hands of human and wings of birds. They have same basic structure like skeletal structure which is humerus, radius, ulna, carpals, metacarpals and phalanges. They are similar in structure but have different functions like flying in birds and gathering food in humans.

HEYYYYYYYYYY PLEASE HELP!!!!!

kodGreya [7K]

Answer:

Velocity

Explanation:

Given the change in positive (direction) over time we are given the velocity formula.

V = Change in direction/Change in time

Since we are given a direction we can rule out speed as well as direction in itself. We can also rule out acceleration because that is the change in Velocity divided by change in time.
