The length of a rectangular sheet of paper is 50 cm and the width is 12 m how many squares

The length of a rectangular sheet of paper is 50 cm and the width is 12 m how many squares with an area of 100 cm2 can be cut from this sheet of paper

Let’s designate the gene that causes the development of albinism in humans as c, then the gene that causes normal skin pigmentation will be designated as C.

Let’s designate the chromosome with the gene that causes the development of hemophilia in humans as Xg, and the chromosome with the gene that causes the development of normal blood clotting as XG.

A man with hemophilia and albinism will be recorded, according to the introduced designations, as cc Xg Y. he will produce two types of spermatozoa – cXg and cY.

A woman who does not have albinism and hemophilia, but who carries both pathological genes, will be recorded as Cc XG Xg. It will produce four types of eggs – CXG, with XG, C Xg, cXg.

The possible offspring of the presented married couple will include the following options:

healthy girls without hemophilia and albinism (CcXG Xg) – 12.5%;

girls with albinism (cc XG Xg) – 12.5%;

boys with hemophilia (C with Xg Y) – 12.5%;

boys with hemophilia and albinism (ccXg Y) – 12.5%;

healthy boys without hemophilia and albinism (СсXG Y) – 12.5%;

boys with albinism (cc XG Y) – 12.5%;

girls with hemophilia (Cc Xg Xg) – 12.5%;

girls with hemophilia and albinism (ccXg Xg) – 12.5%.

Answer: healthy sons will make up 12.5% ​​of possible offspring.
