What else can I help you with?
DNA coding regions that affect the same trait are called?
alleles
What information determines alleles?
Alleles are determined by variations in the DNA sequence of a gene. These variations can result in different forms of the gene (alleles) that can affect traits or characteristics in an organism. Alleles are inherited from parents and can be dominant or recessive, affecting how they are expressed in the phenotype.
How are alleles and mutations linked in the context of genetic variation and inheritance?
Alleles are different forms of a gene that can result from mutations. Mutations are changes in the DNA sequence that can create new alleles. These new alleles can lead to genetic variation, which can affect inheritance patterns in offspring.
Are the genes on a recombinant chromatid the same as the original chromatid?
No, the genes on a recombinant chromatid are a combination of genes from the original chromatids. During crossing over in meiosis, genetic material is exchanged between homologous chromosomes, resulting in a new combination of genes on the recombinant chromatid.
In a chromosome pair connected by a centromere what is each individual chromosome called?
chromatid
How does crossing over affect alleles on a chromatid?
cancer
How genatic material can be rearnged during meiosis?
By crossingover.
DNA coding regions that affect the same trait are called?
alleles
Why meiosis gives 4 different gametes?
Because of the crossingover and independant assortment happens in metaphase1.
What factor besides alleles affect phenotypes?
Enviroment, development, and behavior are all factors besides alleles that can affect phenotypes.
In Model 3 two of the light alleles were lost (through the death of the individual who had these two alleles) before reproduction occurred in the 1st generation how did this affect the distribution of?
In Model 3 two of the light alleles were lost (through the death of the individual who had these two alleles) before reproduction occurred in the 1st generation how did this affect the distribution of the three alleles in this small population?
How do allels affect inheritence?
Alleles affect inheritance because they are the different forms of a gene and for example if you had two plants one of them may inherit two alleles for tall stems two alleles for short stems or one of each. (I hope this helps)
How do mutations affect genetic equilibrium?
by introducing new alleles
What is the study of how alleles affect the generations of offspring?
Genetic engineering
Do alleles control phenotype?
Yes, alleles are variations of a gene that can affect the phenotype of an organism. The combination of alleles an individual carries determines specific traits or characteristics that are expressed.
When a chromosome has made a copy of itself each of the two strands is called this?
When a chromosome has made a copy of itself, each of the two strands is called a sister chromatid. Sister chromatids are identical copies formed during DNA replication and are joined at the centromere.
What information determines alleles?
Alleles are determined by variations in the DNA sequence of a gene. These variations can result in different forms of the gene (alleles) that can affect traits or characteristics in an organism. Alleles are inherited from parents and can be dominant or recessive, affecting how they are expressed in the phenotype.
