Answer:
p = 20
Explanation:
to get p alone you have to do the oposite of what your doing with p
ex) its being divided so you would have to multiply both sides by 4 to get p alone
p = 5x4
Answer:
I would write "terrestrial/lives on land during all life stages" between the frog and pigeon branches.
Explanation:
Jaw evolution has started with fish, so i'd place that before the perch, evolution of four limbs is next and I would plate it between the perch and the frog. Evolution of an egg has ensured that organisms remain terrestrial during all stages of life and don't need to rely on water to lay their eggs. So I would place that between the frog and the pigeon. True mammary glands and true hair, as we know it formed on mammals so i'd place that between the pigeon and the rats (although synapsids evolved similar structures long before birds even existed). And lastly, I would place "walking on two legs" between rats and human branches. Because our ancestors evolved bipedalism relatively late.
Answer:
Inversion
Explanation:
The chromosomal mutations are deletion, duplication, inversion, and translocation.
Inversion is the only one listed
Corrected Question:
The picture shows the dihybrid cross of 2 guinea pigs.
1. What is the genotype of the parents?
2. What is the phenotype of the parents?
3. What is the genotype of their baby guinea pig (in the empty box)?
a. BbRr - black rough fur
b. Bbrr - black smooth fur
c. bbRr- white rough fur
d. bbrr - white smooth fur
Answer:
Genotype of parents is BbRr as seen in the cross.
Phenotype of the parents is black rough furred.
The genotype of the baby in the empty box is bbRR.
Option D
<h3><u>
Explanation:</u></h3>
This representation of the genetic crossing is called as Punnet square, after the name of the scientist who discovered this process to denote the probability of finding the required genotype in a statistical way.
Here both the parents are heterozygous black and rough furred, with the genotype of BbRr.
So the gametes from the parents are = BR, Br, bR, and br from both the parents which are represented in the Punnet square.
Thus we can get 16 types of genetic combinations among the offsprings.
