Answer:
9 normal : 3 striped : 3 spotted: 1 striped and spotted.
Explanation:
The F1 progeny contains no spots or stripes and are considered as normal, it means normal tail and normal head are dominant on their alternative traits. So, it means that the F1 progeny are heterozygous in nature for both of the traits.
The cross between 2 F1 progeny is dihybrid cross of lizards (heterozygous) which will produce offspring in 9:3:3:1 ratio, where 9 are normal, 3 striped which are dominant in the one character, 3 spotted which are dominant in other, and 1 will be stripped and spotted which is recessive in nature.
Answer:
Perma Dorji (PD) and Kesan Choden (KC) are children.
If the number of brother PD has is X, the number of sisters she has is 3X
If the number of brothers KC has is 3X, then the number of sisters she has is 3X-2
Explanation:
The total number of children (brothers and sisters) therefore are:
PDs siblings = 3X+X plus
KCs siblings = 3X2
= 3X+X +3X-2
=6x-2
Let's assume that X is 1, therefore the number of siblings equals
6(1)-2
= 4
Don't forget the PD and KC are also children.
Therefore, the total children in the family is equals to 6
Cheers!
