Suppose that a diploid cell contains 8 chromosomes (2 n = 8). How many different combinations in the gametes are possible?

Biology
1 answer:
zhenek [66]3 years ago
6 0

Answer:

16

Explanation:

A diploid organism that produces gametes will undergo meiosis to do so. Meiosis reduces the chromosomal number in the gametes by half. Hence, each gamete will have 4 chromosomes (haploid,n). Crossing-over will likely occur during the meiotic process leading to recombination in the arrangement of chromosomes in the gametes.

If this occurs, a mathematical expression of 2^n is used to determine the number of possible combinations, where n is the number of chromosomes in the gamete.

Hence, 2^4 = 16 possible combinations of chromosomes in the gamete.

For most genes on the human X chromosome, what percent of XY males with a mutant allele on the X chromosome will express the mut
Nitella [24]

Answer:

D. 100%

Explanation:

In humans, males have only one copy of the X chromosome in their cells. Therefore, human males express all the X-linked genes present on their X chromosomes irrespective of the recessive or dominant nature of the allele. This occurs since males do not have one more copy of the X chromosome to carry another allele for the gene. So, all the X-linked alleles present on the X-chromosomes of the human males are expressed.

For example, human males with genotype X^cY and X^hY express colorblindness and hemophilia respectively. Though, human females express these recessive X-linked disorders in homozygous genotype only.

A certain first-order reaction a → b is 25% complete in 42 min at 25°c. What is the half-life of the reaction?
yan [13]

Answer:

t_{\frac{1}{2}} = 101.16 minutes

Explanation:

For a First order reaction, the rate constant is determined by

k = \frac{2.303}{t} log \frac{a}{a-x}

Where

k= rate constant

t= time required for a reaction

a= initial concentration

x= amount of reactant decomposed in time t

a-x= amount of reactant left after time t

Let the initial concentration be 100

Then

x = 25\\a-x = 75

Substituting the given values in above equation, we get -

k = \frac{2.303}{42} log \frac{100}{75} \\

k = 6.85 *10^{-3}

Also,

k = \frac{0.693}{t_{\frac{1}{2}} } \\t_{\frac{1}{2}} = \frac{0.693}{6.85 *10^{-3}}\\

t_{\frac{1}{2}} = 101.16 minutes
