Xw Xw = White eyes female
XW Xw = Red eyes female
XW XW = Red eyes female
XW Y = Red eye male
Xw Y = White eye male
Red eye female = XW Xw or XW XW
White eye male = Xw Y
XW XW mixed Xw Y
100% red eyes (both male and female)
XW Xw mixed Xw Y
Out of girls, 50% red eyes
Out of boys, 50% red eyes
Both genders have a 50% chance of getting white eyes
I hope this helps!
Answer:
It is homozygous at two gene loci.
Explanation:
An organism may be homozygous or heterozygous for a particular gene. The presence of two identical alleles of a gene in the genome of an organism makes it homozygous for the gene. On the other hand, the presence of two dissimilar alleles of a gene makes the organism heterozygous for the gene.
For instance, AA or aa are homozygous states since two copies of identical alleles (dominant and recessive respectively) are present. The genotype "Aa" is heterozygous since it has one dominant and one recessive allele for a particular gene.
The given genotype "AABbcc" is homozygous for "A" and "c" due to the presence of two copies of dominant and recessive alleles respectively. However, it is heterozygous for the second loci (Bb). Since the recessive allele is present in the homozygous state (cc), it will express itself.

The answer is given below in detail.
Explanation:
When a smoker continues smoking for years, the lungs develops cancer. The lung cancer progresses in the following order:
- The cell lining of the bronchi thickens and forms callus.
- After this step, cilia are lost
- Cells with atypical nuclei starts to appear
- After this tumor is formed
- In the final step, metastasis occur.
