Answer:
The enviornment is important because its where animals interact with nature, materials, and how they live life. Messing with the environment can kill a whole species or even a whole forest. The environment is where animals make their habitat and improve their own homes. Without environments we would not be able to live because the food we need would end up dying or just moving to find another location to live. Without prey or predators, the environment in incomplete and there's a high chance we will overpopulate or just die.
Let's look BB and Bb
They both have the dominant trait which means they both have the same physical appearance (phenotype) , but while BB has both dominant and Bb has one dominant and one recessive that means that although Bb has the same phenotype as BB, it has a different genotype because it has a bit different genetic makeup
Answer: 1/4 (4 out of 16 offsprings express one of the two dominant alleles)
Explanation:
The dominant alleles are A and B
At the end of the cross AaBb x AaBb, 16 offsprings would result. They are as follows: AABB, AABb, AaBB, AaBb
AABb, AAbb, AaBb, AABB,
AaBB, AaBb, aaBB, aaBb,
AaBb, Aabb, aaBb, aabb.
Of all, only 4 offsprings (aaBb, aaBB, AAbb, Aabb) expresses one of the A or B. so 4/16 = 1/4
What genes each parent had for that trait.
Example: In peas, the trait for green peas is dominant (G) and the trait for yellow peas (g) is recessive. If you want the offspring to definitely be yellow, then both parents have to be yellow, with the allele frequency of gg. If both parents were carriers of the yellow gene, but were green (Gg), then there is a 25% chance of having yellow offspring, the rest being green. If one parent is a carrier (Gg) and the other is yellow (gg), then there is a 50% chance of having either yellow or green offspring. If one parent is homozygous (two alleles of the same gene) dominant, then no matter who that parent is paired with, then the offspring will definitely be green.
This can all be figured out through punnett squares
