A tiger cub has a pattern of stripes on its fur that is similar to that of its parents. Where are the instructions stored that provide information for a tiger's fur pattern?

A In cytoplasm inside cells

B On genes within chromosomes

C On the cell membrane

D In the mitochondria

B On genes within chromosomes

Explanation:

All information about a cell are encoded in the genes within the chromosomes. A gene is the smallest unit of hereditary in every living organisms. They contains information about the genetic make up of every life.

Genes are made up of deoxyribonucleic acids.

Genes are usually made in pairs which are homologous and code for each of the character states in an organism.

They are usually passed from parents to offspring. They make it possible for traits in parents to be handed down to their offspring.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
