Answer:

The answer is A.

Explanation:

Lets look at the charges of each part and see which one lines up.

B) The nucleus contains the protons and neutrons. Since the neutrons have no charge and the protons have a positive charge, the overall charge of the nucleus is positive.

C) Electrons have a negative charge.

D) The neutrons have a neutral charge meaning they do not have a positive or negative charge.

The only answer that lines up with the choices is A.

klio [65]

Answer:

All of their sons would be colour blind

Explanation:

Given that colour blindness is X linked recessive condition which means that the gene is located on X chromosome and when present in recessive homozygous condition, it will be expressed. Hence if XC is dominant allele and Xc is recessive allele, XcY and XcXc will be colourblind.

The male has normal vision and males have only one X chromosome so his genotype is XCY.

The female is colourblind and females have two X chromosomes so her genotype is XcXc.

Their children:

XC Y

Xc XCXc XcY

All the sons have XcY genotype where gene for colourblindness is in recessive condition hence all of their sons would be colourblind.
