Is it true that one member of each homologous chromosome pair comes from each gene?

Is it true that one member of each homologous chromosome pair comes from each gene?

Each copy of the homologous pair of chromosomes originates from a different parent; therefore, the copies of each of the genes themselves may not be identical. The variation of individuals within a species is caused by the specific combination of the genes inherited from both parents.

Are a pair of corresponding chromosomes is homozygous?

A pair of corresponding chromosomes is homozygous. One member of each homologous chromosome pair comes from each gene.

What did Thomas Hunt Morgan discover that some genes appeared to be linked They seemed to violate the principle of?

Thomas Morgan discovered that some genes appeared to be linked; This seemed to violate the principle of independent assortment. The farther apart two genes were on a chromosome, the more likely it would be that crossing-over would occur between them.

What stage of meiosis does Synapsis occur?

prophase I
Synapsis is the pairing of two chromosomes that occurs during meiosis. It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them. Synapsis takes place during prophase I of meiosis.

Are genes are located at specific positions on chromosomes?

The genes on each chromosome are arranged in a particular sequence, and each gene has a particular location on the chromosome (called its locus). In addition to DNA, chromosomes contain other chemical components that influence gene function.

How do the location of specific genes compare between homologous chromosomes?

Homologous chromosomes are chromosome pairs, one from each parent, that are similar in length, gene position and centromere location. Homologous chromosomes are similar but not identical. Each carries the same genes in the same order, but the alleles for each trait may not be the same.

What phase do spindle fibers pull homologous pairs to ends of the cell?

anaphase I
In metaphase I, the homologous pairs of chromosomes align on either side of the equatorial plate. Then, in anaphase I, the spindle fibers contract and pull the homologous pairs, each with two chromatids, away from each other and toward each pole of the cell. During telophase I, the chromosomes are enclosed in nuclei.

What is exchanged between homologs during crossing-over?

Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.

Which term describes the specific position of a gene on a chromosome?

​Locus. = A locus is the specific physical location of a gene or other DNA sequence on a chromosome, like a genetic street address. The plural of locus is “loci”.
