A woman with Straight hair marries a man with curly hair who is known to be heterozygous of the trait. What is the chance that their first child will have curly hair?
1 No chance
2 One in two
3 It is certain
4 One in four
Explanation:
A man with heterozygous curly hair is married to woman with straight hair given in question. - The probability of curly hair for the first child is \(50 \%\), since the straight hair gene is dominant and located on X chromosomes.

In pigs, white coat \((\mathrm{W})\) is dominant to black (w). Two white pigs are breed to procedure 9 white and 2 black pigs. What are the genotype of the parents?
1 \(\mathrm{WW} \times \mathrm{WW}\)
2 \(\mathrm{WW} \times \mathrm{WW}\)
3 \(\mathrm{Ww}_{\mathrm{W}} \times \mathrm{Ww}\)
4 \(\mathrm{ww} \times \mathrm{ww}\)
Explanation:
In pig white coat (W) is dominant over black (w). Two white pigs are breed to produce nine white and two black pigs. The genotype parent's in such case is \(\mathrm{Ww} \times \mathrm{Ww}\). Since, correct option is (c).

Extra nuclear inheritance is a consequence of presence of genes in
1 mitochondria and chloroplasts
2 endoplasmic reticulum and mitochondria
3 ribosomes and chloroplast
4 lysosomes and ribosomes
Explanation:
Some characters are governed by non nuclear genes present in mitochondria, chloroplasts or endosymbionts. This phenomenon is called as extra nuclear or cytoplasmic inheritance. - DNA and RNA is the genetic material that carries information from one generation to another. Apart from this genetic material in the nucleus, The cytoplasm also contributes to the inheritance of some characters. Such characters are cytoplasmic inherited characters and this phenomenon is called as cytoplasmic inheritance. It is also called extra nuclear inheritance, because in this type of inheritance factors lie outside the nucleus of the cell. - The cytoplasm contains various cell organelles including mitochondria, chloroplasts are regarded as semi-autonomous as they contain their own genetic material- DNA. Hence cytoplasmic inheritance involves inheritance of mitochondrial DNA and/or chloroplast DNA.
