The reproductive parts in animals produce gametes that fuse and form <u>ZYGOTE</u>.
Okay, hope it helps.
Tree rings are annual growth rings and their thickness indicates how growing conditions were for that year. Index fossils in their type and frequency are indicative of the environment that those organisms grew in and how prolific life was then in that environment. Ice cores drilled through glaciers and ice sheets like in Antarctica tell us about such things as the concentration of greenhouse gases like carbon dioxide (as bubbles in the ice layers) and also about climatic conditions in glacial and interglacial periods.
Well this really depends on if the father is homozygous or heterozygous for type A.
But lets say he is homozygous for right now. That mean if he were to produce offspring with a type O women then all of there offspring would be heterozygous for type A.
If the father was heterozygous for type A and he produced with the same type O mother then the offspring would be either type O or heterozygous type A. In this case there is a 50% chance either way.
Hope this makes sense(;
