Answer:
Explanation:
Honey-colored eyes A is dominant over blue-colored eyes a.
A homzygous honey-colored male (AA) had a baby with blue-eyed female (aa).
AA x aa
Offspring Aa Aa Aa Aa
1. Since A is dominant over a, <u>all the expected offspring would have honey-color eyes with Aa genotype.</u>
2. The genotype of the homzygous honey-color eyes father would be AA while that of the blue-eye mother would be aa.
B IT WOULD BE ACCIDENTAL CAUSE SHE DIDNT MEAN TO CARRY THEM ON HER SHOES
Answer:
Biogas is composed mostly of methane (CH4), the same compound in natural gas, and carbon dioxide (CO2).
Explanation:
Answer:
Species separated by a physical barrier for a long time, suffer allopatric speciation, so they can not interbreed anymore.
Explanation:
Allopatric speciation consists of the geographic separation of a continuous genetic background giving place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flow, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
Vicariance is the geographical separation of an original population into two or more new groups. Discontinuities in the physical environment like rivers, mountains, water, etc., are physical barriers that impede genetic flow between the separated groups.
The process of allopatric speciation involves different steps:
- The emergence of the barrier.
- Interruption in the genetic interchange
- The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
- Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
- Prezigotic isolation mechanisms favored by selection once occurs a secondary contact between the new species in formation.
