yAn LNG po Alam ko e:^In flies, red eye color (Xa) is a sex-linked recessive trait. Black eyes (XA) are the normal colored eyes for flies. What are the chances
that a carrier mom and a black-eyed dad will have (hint: you must use X's and Y's):
a. a red eye male as their next offspring?
b. a black eye female as their next offspring?
2.
3
4.
5 6 7 8 9 10
Answer:
The correct answer is -
a. a red-eye male as their next offspring? = 25%
b. a black eye female as their next offspring? = 25%
Explanation:
The given question says that in flies the red eye color is a sex-linked recessive trait which means it will only appear in the presence of two copies of the recessive allele in females and one copy of recessive allele in male as there is only one copy of X chromosome is present in males the other chromosome is Y.
So, the genotype of carrier mom would be XaXA and normal black eye male would be XAY, then cross between these flies:
XA Y
Xa XaXA XaY
XA XAXA XAY
On the basis of red eye male would be XaY = 1/4 = 25%
and the black eye female would be XAXA = 1/4 = 25%

how do radiation, conduction, and convection affect the atmosphere?
Answer:
Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere.

Analyze the effects of DNA mutations
on the
of an organism.
Answer:
DNA mutations or Chromosomal mutations are also called chromosomal aberrations, chromosomal abnormality, or chromosomal disorders, all indicating a possible alteration in the morphology and structure of the chromosome.
DNA mutations lead to abnormalities in the function of the cell and organism, as chromosomal or DNA mutations can result in abnormal gene numbers or positions.
These are known to cause different genetic diseases that can be hereditary and are transferred from one generation to another.
These mutations, however, do not always affect the functioning of the cell as some mutations might affect regions of chromosomes that do not make up the genetic makeup of the organism.
Even though gene mutations are usually more severe than chromosomal mutations, some chromosomal mutations might result in gene mutations.
