Calico cats are nearly all females because the alleles for the different colors that appear are carried on the X chromosomes. Males are never multicolored because they can only carry one form of the a?

It is most common for calico cats to be female because the alleles for the different colors are carried on the X chromosome, which female organisms have two of (XX in female versus XY in males). Male calicos do exist and can be multicolored, but they are rare because they only carry one X chromosome.

What are the two different alleles for a gene?
I think it is Dominant and recessive.
Why do you have more genotypes than phenotypes?
Because those alleles segregate, or seperate, and combine again to make different alleles, thus making different phenotypes.
How similar are two people with respect to chromosomes genes and alleles?
No two people in the world are exactly the same except identical twins. Their chromosomes are exactly the same because the egg split in two and formed two identical embryos.
Why does a puppy always have two alleles for every trait?
Because of homologous pairs of chromosomes. One chromosome from the puppies mother and one from the father make up the 78 chromosomes of dogs. One allele on the mom chromosome and one on the dad chromosome, even if there are more than two alleles for the trait only two will be represented in the genome.
Simplify meiosis into its basic events?
Homologous chromosomes pair up. Nonsister chromatids exchange segments in a process called crossing over. Because alleles etc.
What is the relationships between chromosomes genes and alleles?
alleles are the various types of options that is chosen by the gene. The gene is the segment of DNA that codes for the protein. Genes are found on chromosomes. Chromosomes contain multiple genes.
Do homologous chromosomes always have identical alleles?
no they don't necessarily have to have the same alleles but they have the same genes. Homozygous chromosomes would have the same allele for a particular gene and heterozygous chromosomes would have different alleles for a particular gene.
What chromosomes are sex linked genes located?
The sex chromosomes, mostly on the X sex chromosome because it is much larger than the Y chromosome and has more alleles.
Why do the chromosomes in a homologous pair differ from one another?
They have the same length and gene locus but differ in terms of alleles. An allele is a form of a gene, differing from other alleles of the gene by a few bases at most and occupying the same locus as the other alleles of that gene. The gene locus is the position of a gene on a chromosome. Hope that helped! They have the same length and gene locus but differ in terms of alleles.

Why sister chromatids could not have different alleles?
They cannot be different because when DNA copies, it makes an exact copy of itself. Making it so that the alleles are the same. So it would be impossible for the alleles to be different.
What kind alleles does a heterozygous individual have?
a heterozygous individual has different alleles because one is dominant but the other is recessive.
Why are rainbows Multicolored?
Rainbows are multicolored because the white light is refracted spliting it apart into its individual colors
How are chromatin and chromosomes different different?
they are different because they are both ugly and both have a...

During meiosis the process of crossing over results in new combinations of alleles because?
genetic material is exchanged between chromosomes during this process.
This child is you simply the best of you you could conceive a hundred times and never achieve the same results explain this statement using the terms homologous chromosomes and alleles?
I had to do this too. Because of Meiosis, each egg and sperm cell have completely different alleles that are never the same. That is because during meiosis, the homologous chromosomes line up together during synapsis and then they cross over. Crossing over allows each new gamete to be genetically different from the other. That is why they say they could never achieve the same results even if they conceive a hundred times. Hope this helped
