Red-green color blindness is an X-linked recessive disorder. A woman with normal vision whose father was colorblind has children
andrey2020 [161]

Answer:

The probability of their first child being colourblind is 1/4

Explanation:

Red-green color blindness is an X-linked recessive disorder.

A woman with normal vision whose father was colorblind has children with a man with normal color vision.

In an X-linked condition, the males only need to get one copy of the affected allele to have the condition and this copy is also inherited by a female offspring.

So in this case, the woman receives the affected recessive allele copy from her dad but since she still has normal vision, she received the normal copy from her mom so she is heterozygote for the trait.

The woman with normal color (XRXr) has a father who is color blind (XrY) has children with a normal man (XRY)

The cross would be

XRXr x XRY

XR Xr

XR XRXR XRXr

Y XRY XrY

Probably of having an affected child is 1/4. Thus, the probability of their first child being colourblind is 1/4

Which statement accurately describes how identification of individuals through the use of genetic engineering is possible? 
Andre45 [30]

The identification of an individual by the means of genetic engineering is possible because the Y chromosomes in the males does not experience any crossing-over as there is only a single Y chromosome present in a human male.

The mitochondrial DNA is passed from the mother to child in the cytoplasm of the cell, and it is passed on without any changes. The X chromosome is can be passed from a mother to her son as he will receive Y chromosome from his father.

Hence, the correct answer is 'Option B - The Y chromosome does not experience crossing over'.
