Genes on the X and Y chromosomes, which determine sex in humans, do not occur in pairs. These are called sex-linked genes, with males having one X and one Y chromosome and females having two X chromosomes. This results in differences in gene dosage between males and females for genes on the sex chromosomes.

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 total base pairs are in all the mammalian genes?
The exact number of base pairs in all mammalian genes is not known due to variations between species. However, the human genome contains approximately 3.2 billion base pairs. Mammalian genomes are generally similar in size to the human genome, so the total base pairs in all mammalian genes would be around this range.
How many genes are found on each of your chromosomes?
Humans have 22 pairs of autosomes and one pair of sex chromosomes (XX for females, XY for males). Each autosomal pair contains approximately 1,000-2,000 genes, while the X chromosome has around 1,500 genes and the Y chromosome has around 200 genes.
Organisms inherit genes in pairs from each what?
Organisms inherit genes in pairs from each parent during sexual reproduction. Each parent contributes one set of genes, forming pairs that determine the genetic makeup of the offspring. This process ensures genetic variation and diversity in offspring.
Which of the following has the largest genome and the fewest genes per million base pairs?
The largest genome typically belongs to amoebas, like Amoeba dubia, which can have billions of base pairs. Organisms with large genomes tend to have fewer genes per million base pairs due to the presence of repetitive and non-coding DNA sequences that lower the gene density.
Explain why the majority of genes in an organism occur in pairs.?
Genes come in pairs because Genes are in chromosomes and chromosomes come in pairs as well.

Organisms inherit genes in pairs?
YES!
What do organisms inherit genes in pairs from?
your parent(s)
What are the genes called in gene pairs?
incomplete dominance
How do combinations of genes occur?
through dominate and recessive genes
What is the Cumulative effect of two pairs of genes?
The cumulative effect of two pairs of genes refers to the combined influence of both pairs on an organism's phenotype. This can result in additive effects, where the traits from each pair of genes contribute independently, or epistasis, where the effect of one pair of genes masks or modifies the expression of the other pair. Ultimately, the interaction between these gene pairs determines the overall phenotype of the organism.
What Organisms inherit genes in pairs one from each?
Parent
What do forces always occur in?
Forces always occur in pairs known as action-reaction pairs, according to Newton's third law of motion. This law states that for every action, there is an equal and opposite reaction.
What are mutated genest Mutated genes are mutated genes?
i dont no
What does six gene pairs mean?
Genes usually come in pairs because an organism can inherit a given gene from both parents. Six genes is not a lot, that would be a small portion of a genome.
Do action-reaction forces always occur in threes or pairs?
Pairs!
