What is a genotype composed of?
Genotype is the genetic make up of an organism both expressed (phenotype) and unexpressed.Example: AaeeDndn is the genotype which includes unexpressed (recessive) alleles a and dn.Expressed dominant traits A and Dn as well as expressed recessive traits (ee). Note that expressed recessive traits have to be homozygous.
What is the traits produced by an organism's genes?
A genotype is the entire genetic make up of an organism. The phenotype is the actual expressed traits or characteristics found within an organism. The distinction between genotype and phenotype can be made based on dominant and recessive genes.
What type of cell make up unicellular organisms?
Eukaryotic cell make up unicellular organisms.
Do both alleles of a gene pair make up an organisms genotype?
If by gene pair, you mean the two copies of each gene present in a diploid cell, then yes. Both alleles make up an organisms genotype, though they might not both be expressed in the phenotype, if one is recessive for instance.
What is the term that describes when both alleles show up equally?
homozygous dominant or recessive depending on what gene it is
Of nucleic acids carbohydrates proteins and lipids which do cells produce the most of and why?
Cells produce the most proteins because they primarily make up the human body. All our phenotypes (traits) are expressed from DNA by proteins.
Why are cells considered to be the basic unit of living organisms?
Because cells make up tissues and tissues make up organs and organs make up systems and systems make up organisms. Also unicellular organisms are considered living and they only have one cell.
What is the difference between a gene allele Chromosome and trait?
Alleles are alternate versions of genes that code for certain phenotypes, or traits. The traits of an individual are a result of the interaction between their genotype (alleles) and the environment.
What is animal tissue?
tissues that make up organs that make up organisms
How are recessive and genes related?
If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation. Two alleles together make a genotype, which is the inherited combination of alleles. Alleles: different versions of the same gene. Heredity: determined by genes. Genes: piece of DNA that shows the cell how to make a protein it needs.

What is the role of DNA in determining and organisms traits?
Yes, the DNA molecule is made up of segments of coding called Genes. Each gene codes to make a different protein or genetic characteristic.
