Answer:
1/2 wWBb , White wool and brown eyes.
1/2 wWbb , White wool and blue eyes.
Explanation:
White wool (W) is dominant over black wool (w).
Brown eyes (B) is dominant over blue eyes (b).
A sheep with black wool (ww) and brown eyes (Bb) is crossed with a sheep with white wool (WW) and blue eyes (bb).
<h3>wwBb x WWbb</h3>
If there is independent assortment between genes, the genotypes of the first parent's gametes will be wB and wb. The gametes of the second parent can only be Wb.
<u>The resulting offspring will be:</u>
- 1/2 wWBb , White wool and brown eyes.
- 1/2 wWbb , White wool and blue eyes.
Answer:Amphibians evolved during the middle of the Devonian period (416 to 359 million years ago) from the lobe-finned fish of the vertebrate class Sarcopterygii. Species within the genus Ichthyostega (members of the Labyrinthodontia subclass) are considered by some scientists to be the earliest amphibians.
Explanation:
Initially, when scientists were first using the taxonomy system to classify living organisms there were only considered to be 2 kingdoms: plants and animals. However, when the microscope was invented, scientists were able to observe differences in organisms at the cellular level! They were also able to observe microscopic living organisms like bacteria that they had not been able to observe before. Scientists realized it was necessary to add 4 new kingdoms to account for the observations they had not seen before the invention of the microscope.
Answer:
They are all part of the Kingdom Animalia
