65. In dogs, wire hair (H) is dominant over straight hair (h). Two dogs produce offspring as shown in the Punnett square below.

valentina_108 [34]

About the question:

I failed to find the complete question with the Punnett square, so in the answer and explanation I will propose five options for crosses between dogs with different genotypes, and for each option, I will remark the percent of the offspring that is expected to have wirehair. You just need to look for the option that matches your Punnett Square.

Answer:

Option 1: HH x HH ----> 100% of the progeny is wire-haired, HH
Option 2: HH x Hh---> 100% of the progeny is wire-haired, HH + Hh
Option 3: Hh x Hh --->75% of the progeny is wire-haired, 25% HH + 75% Hh
Option 4: Hh x hh ---> 50% of the progeny is wire-haired, Hh
Option 5: hh x hh ----> 0% of the progeny is wire-haired

Explanation:

You will find the complete explanation in the attached files due to technical problems

Abundance of the different bases in the human genome. Results on the human genome published in Science (Science 291:1304-1350 [2

Alexxx [7]

Answer:

A typical Human Cells= $3.1428*10^9$ residues.

T typical Human Cells= $3.1428*10^9$ residues.

G typical Human cells= $2.6772*10^{9}$ residues.

C typical Human cells= $2.6772*10^{9}$ residues.

Explanation:

Given:

Number of human genome in pairs=2.91*10^9 base pair

Number of Human genome single bases= $2*2.91*10^{9} =5.82*10^{9}$ bases

We know that human genome are diploid, Total Human genomes will bases will be $2* 5.82*10^{9}=1.164*10^{10}$ bases

Since A is 27%:

A typical Human cells= $0.27*1.164*10^{10}$

A typical Human Cells= $3.1428*10^9$ residues.

The Number of T and A residues are same in human genome. So,

T typical Human cells= $3.1428*10^9$ residues.

Since A and T combined form 54% of human genome then G and C form 46% combined and 23% each.

G typical Human cells= $0.23*1.164*10^{10}$

G typical Human cells= $2.6772*10^{9}$ residues.

The Number of G and C residues are same in human genome. So,

C typical Human cells= $2.6772*10^{9}$ residues.

Environmental factors can influence natural selection because they can increase or decrease

timama [110]

Answer:

the amount of genetic variation in a population.

Explanation:

The proportion of the members of a population possessing beneficial allele due to natural selection will increase with time while the proportion of those possessing a harmful allele will decrease with time. After many generations, all the members carrying the harmful allele will die out leaving only those with the beneficial allele. The result is a genetic variation of the population with time.
