Si se cruza una vaca de piel con manchas heterocigota, sin cuernos, con un toro de piel con manchas homocigota con cuernos heterocigota.
La ausencia de manchas y de cuernos se presenta en estado recesivo.
A. Cuál es la probabilidad de obtener un ternero sin manchas con cuernos?
B. Cuál es la posibilidad de obtener un ternero con manchas y cuernos?
C. Cuál es la posibilidad de obtener un ternero sin manchas ni cuernos?
D. Cuál es la posibilidad de obtener un ternero con manchas sin cuernos?

The answers to these questions are the following:

A- The chances to have a spotless animal with horns is 0 % because the father is a spotted animal (homozygous) and this trait is dominant

B- The chances to have a spotted animal with horns is 75 % because the father has horns (heterozygous) and this trait is dominant

C- The chances to have a spotless animal without horns is 0 % because the father is a spotted animal (homozygous) and this trait is dominant

D-The chances to have a spotted animal without horns is 50% because the father has horns (heterozygous) and this trait is dominant

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
