Identical pairs of alleles are called homozygous alleles.


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


Chromosomes normally occur as homologous pairs in?

Chromosomes normally occur as homologous pairs in diploid cells, with one chromosome in each pair inherited from each parent. These pairs are similar in terms of size, shape, and genetic content, allowing for genetic diversity and recombination during sexual reproduction. Homologous chromosomes carry the same genes, but may have different variants (alleles) of those genes.


How many alleles are in the human body?

i dont know- but there are 23 pairs of alleles (including the xx or xy ones)


Pairs of alleles ( genes ) that are the same i.e. GG nn are called what?

Pairs of alleles that are the same, such as GG or nn, are referred to as "homozygous." In these cases, both alleles at a particular gene locus are identical, which can influence the expression of traits in an organism. If the alleles are different, such as Gg or Nn, the organism is considered "heterozygous."


When a trait has two identical alleles what is it called?

In humans a trait can be determined by one pair of many pairs of?

alleles.


Mendel observed that pairs of alleles were separated or segregated in gametes and that they were rejoined in fertilization. We know that pairs of are segregated in and then are rejoined through fertil?

Mendel observed that pairs of alleles are segregated during meiosis, the process of gamete formation, where homologous chromosomes are separated into different gametes. During fertilization, these gametes combine, rejoining the alleles from each parent to form a new genotype in the offspring. This segregation and rejoining of alleles is fundamental to the inheritance of traits.


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
