What species originally eliminated the wolves in yellowstone so that they had to be reintroduced?.

bezimeni [28]

Humans were the species that originally eliminated the wolves in Yellowstone so that they had to be reintroduced.

I was in the year 1800 that an expansion in an area caused native predators and preys to come close the the domestic livestock. The wolves, being predators, began to feed on the domestic livestock due to its abundance and closeness.

To stop the wolves from feeding om domestic livestock, it were the humans who became the reason for wolves being eliminated. The people in those times were unaware of the natural understanding of ecosystems and hence considered wolves to be a threat.

It was in the 1970's that national awareness was made to protect endangered species. Hence, an effort was the made to reintroduce the wolves into Yellowstone.

In horses, black color(B) dominates chestnut color(b). The trotting gait(T) dominates the pacing gait (t). A cross is made betwe

bulgar [2K]

Answer:

<h2>a. BbTt;</h2><h2>b. BbTt X BbTt ;</h2><h2> Parent 1: BT bt Bt bT </h2><h2> Parent 2: BT bt Bt bT ;</h2><h2>c. BBTT , BbTt , BBTt , BbTT , BbTt , BbTt , BBTt , BbTT , BBTt , Bbtt , BBtt , BbTt , BbTT , bbTt , BbTt , bbTT.</h2><h2> d. 12:1:1:2</h2>

Explanation:

As given Block color is dominant over chesnut color, so B is dominant over b.

Chestnut color=bb ;

Trotting gait is dominant over pacing gait, so T is dominant over t .

Pacing gait=tt

Now; cross between

(a) homozygous black, pacing gait is= BBtt; and horse homozygous for chestnut color, trotting gait is= bbTT

BBtt x bbTT

gametes are ; Bt and bT,

Progeny are BbTt, BbTt,

All progeny will be BbTt heterozygous Black color and heterozygous trotting gait

b. a cross is made between two horses, both of who are heterozygous black trotter = BbTt X BbTt

Possible gametes of each parent are;

Parent 1: BT bt Bt bT

Parent 2: BT bt Bt bT

c. Punnett square and all the possible gene combinations that results are;

Cross between these gametes

BT bt Bt bT

possible gene combinations ; BBTT , BbTt , BBTt , BbTT , BbTt , BbTt , BBTt , BbTT , BBTt , Bbtt , BBtt , BbTt , BbTT , bbTt , BbTt , bbTT.

d. expected phenotype ration of the offspring.

Black color and trotting gait horse 12: chestnut and trotting gait horse 1: Black color pacing gait horse 1: chestnut and trotting gait horse 2.

so 12:1:1:2
