What does alleles always come in?
Alleles are generally inherited in pairs, except for alleles on the X and Y sex chromosomes in males.
Identical pairs of alleles are called what?
homozygous
In humans a trait can be determined by one pair of many pairs of?
alleles.
When two different alleles occur in a cell?
A heterozygous condition.
Is there a greater chance of crossing over between some pairs of alleles than between others?
Yes there is. Some alleles are closer together and less likely to separate than other alleles. This is typically referred to as linkage.
What does alleles always come in?
Alleles are generally inherited in pairs, except for alleles on the X and Y sex chromosomes in males.
Do all heterozygous pairs of alleles produce an intermediate?
No
Identical pairs of alleles are called what?
homozygous
How many alleles are in the human body?
i dont know- but there are 23 pairs of alleles (including the xx or xy ones)
When a trait has two identical alleles what is it called?
Homologous pairs
Do all heterozygous pairs alleles produce an intermediate phenotype?
No
A different form of a gene?
genotypes
What are pure alleles?
Alleles come in pairs. Organisms inherit one allele from each parent organism with sexual reproduction. If the alleles are the same, they could be said to be pure alleles. The science term is monozygous.
In humans a trait can be determined by one pair of many pairs of?
alleles.
What does forces do?
Forces always occur in pairs. They even have reaction force pairs occur when there is no motion
What is when a group of gene pairs acts together to produce a single trait?
alleles
What does it means to have homologous chromosomes?
the gene's alleles are found in matched chromosome pairs
