the frequencies with which the corresponding traits occur together in offspring.
The y chromosome, which only contains a few hundred genes.
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
A deletion mutation can take genes away from a chromosome.
Can each chromosome usually contain multiple genes? yes each chromosome usually contains more than one gene.
The farthest apart two genes are located on a chromosome the less likely they are to be inherited together. If two genes are on the same chromosome and rarely assort independently the genes are probably located close to each other.
Gene map.
The number of genes varies. Most of any chromosome consists of non-coding DNA, which does not contain any genes. Each chromosome has many chromatins. One gene consists of many chromatins. Therefore, one chromosome could have many genes.
The genes that are carried on the same chromosome are called as the linked genes.
Allele
The y chromosome, which only contains a few hundred genes.
Genes on the same chromosome are said to be linked.
There are thousands of genes in a chromosome.
The Y chromosome is smaller than the X chromosome and contains fewer genes. It carries the genes necessary for determining male sex and some other genes, but it lacks many of the genes present on the X chromosome. This is why the Y chromosome does not carry any alleles in the same way that the X chromosome does.
no
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
A deletion mutation can take genes away from a chromosome.
Most homologous pairs look alike. They carry genes for the same characteristics and line up on the chromosome in the same order!
