DNA is composed of long strings of nucleic acid sequences, but not all of them code for proteins. The ones that do are called genes. Alleles are different versions of a certain gene. For example, the gene that codes for blood type has 3 different alleles, A, B, and O. The genes that code for hair and eye color also have many different alleles.

∙ 10y agoA gene is a segment of DNA that codes for a functional product (i.e. a protein). An allele is an alternate version of a gene.
For example, in a gene that codes for fur colour in rabbits, the two alleles are B and b.
B and b are both versions of the same gene - but they may result in a different phenotype (physical trait).

The condition in which genotypes have identical alleles?
homologous
What information does a Punnett square provide?
Possible alleles in the gametes of the parents
How are phenotypes and genotypes related to natural selection?
Natural selection favours phenotypes that bestow a reproductive advantage, thereby increasing the frequency of alleles (genotype) producing those phenotypes.
What genotype is produced by the phenotype B?
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.
What information must you know to determine the phenotypes of different genotypes for a gene with two alleles?

How are the genotype and phenotype of parents related to the genotype and phenotypes of offsprings?
The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.
Which genotypes have dominant phenotypes?
The genotypes in which one or more alleles is dominant.
The condition in which genotypes have identical alleles?
homologous
What genotypes is heterozygous?
A heterozygous genotype, is the genetic makeup of different alleles.
What are multiple-allele traits?
Traits governed by multiple alleles are controlled by three or more alleles, rather than two. An example in humans is the ABO blood group system. There are three alleles in the ABO blood group system, IA, IB, IO. These three alleles can produce six genotypes, AA, AO, BB, BO, AB, OO. These genotypes can produce four different phenotypes, A (genotypes AA or AO), B (genotypes BB or BO), AB, (genotype AB) and O (genotype OO).
The frequencies of alleles and genotypes remain constant from generation to generation unless?
There is evolution.

How are the genotypes of parents related to the genotypes and phenotypes of the offspring?
alleles are variations of genes
What genotype is produced by the phenotype B?
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.
What do the letters inside the punnent square stand for?
The letters on the outside are the genotypes of two parents. Inside are the possible genotypes of possible offspring of the two
