I think it will be B not fully sure
Answer:
The results will be 50% heterozygous black dogs and 50% yellow dogs.
Explanation:
A punnet square can be described as a diagrams which predicts the outcomes of a cross being made.
A dominant trait can be described as the trait that dominates and masks the effect of the recessive trait. A recessive trait can be described as a trait that gets suppressed by the dominant trait.
When the two alleles of a gene are similar for a trait, they are said to be homozygous. When the two alleles of a gene are different, they are termed as heterozygous.
A cross between the heterozygous black fur dog with a yellow fur dog will show that there are 50% chances that the offsprings born will be heterozygous black as one of the parents or there is a 50% chance that they will be yellow as the recessive parent dog.
I’m pretty sure the answer is dust, if not please let me know.
Answer:
Rock layers are correlated if they both contain the same fossils.
Explanation:
For the equation y = a(x - h)^2 + k, the vertex is at (h, k), and the focus is at (h, k + 1/4a).
We first complete the square of the equation:
y = x^2 - 2x - 3
y = (x - 1)^2 - 4
Following this format, a = 1, h = 1, k = -4.
Then the vertex is at (1, -4), and the focus is at (1, -4 + 1/(4*1)) which is (1, -15/4).
