Consider a population of cells that doubles every hour and begins with cells. What is the rate of growth of the cell population

ehidna [41]

<h2>Rates of Population Growth</h2>

Explanation:

<em>Growth is precisely defined for microbes as increment in number of cells, not size</em>
Development rate is change in cell numbers per unit time. Age time is the time it takes for a cell to double. Also called doubling time.
Development rates allude to the rate change of a particular variable inside a particular time span and given a specific setting.
r = (births-passings)/populace size or to get in rate terms, <em>simply increase by 100</em>
The populace is so a lot greater, a lot more people are included. In the event that a populace develops by a consistent rate for every year, this inevitably indicates what we call exponential growth..

Child 2 is polydactylous, otherwise normal; Child 4 has cystic fibrosis and is polydactylous.What is the genotype of the mother?

satela [25.4K]

Answer:

PpCc; ccpp; ccPp; 1/2

Explanation: The complete correct question is as follows

A polydactylous woman, otherwise normal, marries a healthy normal man. Their four children have the following phenotypes:

Child 1 is normal in all respects; Child 3 has cystic fibrosis, otherwise normal Child 2 is polydactylous, otherwise normal; Child 4 has cystic fibrosis and is polydactylous. A. What is the genotype of the mother? B. What is the genotype of child 3? C. What is the genotype of child 4? D. What is the chance that child 1 is heterozygous for cystic fibrosis?

We represent the traits of the parents with the following

P= Polydactyly

p=normal

C= normal

c= abnormal (cystic fibrosis

A. What is the genotype of the mother

Mother PpCc (polydactylous)

Father: ppCc (healthy normal)

B. What is the genotype of child 3?

Applying the mendel's cross link between the mother's genotype and father's genotype,

PpCc × ppCc

Child 3 will be ccpp (abnormal with cystic fibrosis)

C. What is the genotype of child 4?

Applying the mendel's cross link between the mother's genotype and father's genotype,

PpCc × ppCc

Child 4 will be ccPp

D. What is the chance that child 1 is heterozygous for cystic fibrosis?

Applying the mendel's cross link between the mother's genotype and father's genotype,

PpCc × ppCc

Child will be Cccc

The chance is 1/2
