What is the probability of producing a roan (red and white) cow when a white cow is crossed with a red cow? Cross: RR x WW

A cross between a roan bull (Ww) and a white cow (ww) produces roan and white phenotypes in a 1:1 ratio.

Explanation:

Two alleles are influencing the color of the hair of the cow-W red and w white.

These alleles show that a hybrid Ww has red hair. The genotype of the bull is Ww, WW is red and ww is white. So, mixing the red and white cows is 1:1.

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)]
