What else can I help you with?
Traits are determined by pairs of genes called?
The two chromosomes (two "X" shapes) that are in a pair are generally called "homologous chromosomes". A pair of "chromatids" make up the two arms of a single chromosome.
Do codominant alleles assort independently?
Yes, codominant alleles assort independently during Mendelian inheritance. This means that the inheritance of one pair of alleles does not influence the inheritance of another pair of alleles on different chromosomes. Each allele segregates independently into gametes during meiosis.
What are a pair of genes that are identical called?
A pair of genes that are identical are called alleles. Alleles are different forms of the same gene that occupy the same position on homologous chromosomes.
During prophase each pair of chromosomes is attached to each other by the?
During prophase, each pair of chromosomes is attached to each other by structures called homologous chromosomes. These homologous chromosomes have similar genes but could have different alleles.
Describes the allele that is fully expressed when carried by only one of a pair of homologous chromosomes?
The allele that is fully expressed when carried by only one of a pair of homologous chromosomes is called a dominant allele. Dominant alleles mask the expression of recessive alleles when present in the genotype.
What does sex linked alleles mean?
Sex linked genes occur only on the X or the Y sex chromosomes.
Traits are determined by pairs of genes called?
The two chromosomes (two "X" shapes) that are in a pair are generally called "homologous chromosomes". A pair of "chromatids" make up the two arms of a single chromosome.
What are alleles passed from parent to child on a sex chromosomes?
They are sex-linked genes.
Do codominant alleles assort independently?
Yes, codominant alleles assort independently during Mendelian inheritance. This means that the inheritance of one pair of alleles does not influence the inheritance of another pair of alleles on different chromosomes. Each allele segregates independently into gametes during meiosis.
When a pair of chromosomes contains different alleles for a trait that trait is called a what when a trait has two identical alleles it is called?
2 different alelles - heterozygous Same alelles - homozygous
What are a pair of genes that are identical called?
A pair of genes that are identical are called alleles. Alleles are different forms of the same gene that occupy the same position on homologous chromosomes.
Why are x linked alleles expressed in males even if they are recessive?
X-linked are not recessive nor dominant. X-linked just do not show. On the sex-linked chromosomes the Y chromosome of the X-Y pair dominates the trait whether its recessive or dominant!Actually, all x-linked alleles are expressed because males only have one x-chromosome, so whatever is there, dominant or recessive, is expressed.
During prophase each pair of chromosomes is attached to each other by the?
During prophase, each pair of chromosomes is attached to each other by structures called homologous chromosomes. These homologous chromosomes have similar genes but could have different alleles.
Why do alleles occur in pairs?
7th grade science is a pain ain't it.... Paired Chromosomes.
Describes the allele that is fully expressed when carried by only one of a pair of homologous chromosomes?
The allele that is fully expressed when carried by only one of a pair of homologous chromosomes is called a dominant allele. Dominant alleles mask the expression of recessive alleles when present in the genotype.
Alleles found on the same chromosomes are what?
Alleles found on the same chromosome are said to be linked. This means they tend to be inherited together and show a lower rate of recombination. Linked genes are inherited as a group and do not assort independently during meiosis.
How can new combinations of alleles be created when genes are linked?
New combinations of alleles can be created when genes are linked through a process called crossing over during meiosis. Crossing over occurs when homologous chromosomes exchange genetic material, resulting in the mixing of alleles between the two chromosomes. This process leads to the creation of new combinations of alleles and contributes to genetic variation in the population.
