The brown skin trait is dominant over the black skin trait in cows. If two heterozygous brown skin cows are crossed, what is the brown-skinned offspring?

B = Brown Skin

b = black skin

                             B      b

                  B        BB   Bb

                  b         Bb   bb

Hope this helped :D

The chances of a homozygous brown skin cow is 25%

The chances of a heterozygous brown skin cow is 50%

The chances of a homozygous black skin cow is 25%

The chances of a heterozygous black skin cow is 0%

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
