A single variable.

In an experiment we are trying to figure out how one thing (independent) effects another thing (dependent) so we want to keep everything constant. We want that experiment to be controlled so nothing else is effecting our dependent variable. That way we can be 100% sure that any change to our dependent is due to our independent variable. Hope that makes sense

Ivanshal [37]
We'll make the alleles: Cc.

C is a healthy parent, and c is the cystic fibrosis (recessive).

If you make a punnett square and the parents are both Cc (healthy), then you would get CC, Cc, Cc, and cc. That cc is a 25% chance that the offspring will have that, which means there is a 25% chance the child will have cystic fibrosis.

Two healthy parents can have a child with cystic fibrosis if both the parents have the dominant allele and recessive allele, if both the parents have heterozygous alleles.

tester [92]

Answer:

Each species has a specific identifying number of chromosomes. For example, a cat, <em>Felis catus</em>, has 38 chromosomes, while corn, <em>Zea mays</em>, has 20 chromosomes each chromosome carries specific genes that are unique to that chromosome.

Explanation:

Chromosomes vary in shape and number among living beings. For example, the bacterial chromosome is a unique circular molecule, while human beings have 46 lineal chromosomes arranged in pairs (23 pairs). The total number of chromosomes is specific to each species, and it is denoted as the "chromosomic dotation" of the species.

Genes are the hereditable units that transmit the information needed to specify traits, from parents to offspring, generation to generation. Genes are arranged in sequence in the chromosomes. A chromosome might contain hundreds of thousands of genes.

Genes vary in size and shape.  They are composed of pairs of bases, and these sequences also vary in number, producing genes of different lengths. In general, genes code for proteins. Proteins create the organism tissues and perform or carry out specific functions in the organisms, controlling almost all processes and chemical reactions.

Each chromosome carries <u>specific</u> genes that code for <u>specific </u>proteins that have <u>specific</u> functions in the organisms. Each chromosome carries information to synthesize different proteins needed to accomplish a certain function. But <u>not all chromosomes carry the same gene sequences</u>. Only homologous chromosomes carry information for the same trait, but even this information is not necessarily the same. They might have the same gene but different alleles.
