Question

If a colour blind lady marries a normal man, their children will be-
A. Normal daughters and normal sons
B. Normal sons and carrier daughters
C. Colour blind sons and carrier daughters
D. Colour blind sons and colour blind daughters

Answer 1

Hint: The technique through which an offspring acquires predisposition to the traits of its parent cell is commonly referred to as heredity. During cell division and fertilisation, recombination and segregation of genes initiate the process of passing genetic features from parents to offspring. Heredity is the total of all biological processes that result in the genesis of a new creature that is similar to its type but differs in some ways due to the genes and their interactions with the environment.

Complete answer:
Option A: When a colorblind woman marries a man with normal eyesight, her daughters become carriers for the condition, and all sons become colorblind.
So, option A is not correct.
Option B: The female is colorblind ($X^cX^c$) and the father is normal, according to the query (XY). The condition will be passed along to \[100\] percent males ($X^cY$) from the colorblind mother, while \[100\] percent daughters will have normal eyesight but will function as carriers.
So, option B is not correct.
Option C: When a colorblind woman marries a guy with normal eyesight, her daughters will be carriers of the disease, and her sons will all be colorblind. This can be explained by
So, option C is correct.
Option D: Colourblindness is a recessive sex-linked trait. All sons will be colorblind, and all daughters will carry the gene for color blindness.
So, option D is not correct.

Hence, Option C is the correct answer.

Note:
Mendel’s laws of inheritance-:
Law of Dominance- Mendel's first law of inheritance is also known as that. Hybrid children will only inherit the dominant characteristic in the phenotype, according to the law of dominance. The repressed alleles are referred to as recessive traits, whereas the alleles that determine the trait are referred to as dormant traits.
Law of Segregation- The law of segregation asserts that two copies of each hereditary component segregate during gamete creation, resulting in offspring inheriting one element from each parent. In other words, during gamete production, allele (alternate version of the gene) pairs segregate and re-unite at random during fertilisation.
Law of Independent Assortment- The law of independent assortment, sometimes known as Mendel's second law of inheritance, asserts that during gamete production, a pair of traits segregates independently of another pair. Different qualities have an equal chance of occurring together since the distinct hereditary variables assort independently.
