What is the name of a photograph of an individual's chromosomes organized into groups?
A karyotype is the name for a photograph showing an individual's chromosomes arranged in pairs and in order according to size and structure. This visual representation helps identify any genetic abnormalities or chromosomal disorders.
What is another name for a chromosome?
Homologous chromosomes are chromosome pairs of the same length, centromere position, and staining pattern, with genes for the same characteristics at corresponding loci. One homologous chromosome is inherited from the organism's mother; the other from the organism's father.[1]
What is the name of the chart used to determine a person's sex?
The chart used to determine a person's sex is called a karyotype chart. This chart displays the chromosomes found in an individual's cells, which can help determine their biological sex based on the presence of XX (female) or XY (male) chromosomes.
What homologous pairs of chromosomes line up in the middle of the spindle during meiosis name the phase one or two?
Homologous pairs of chromosomes line up in the middle of the spindle during meiosis I in the metaphase stage. This alignment is essential for ensuring proper segregation of chromosomes into daughter cells.
What is the name when homologous chromosomes sometimes stick together but do not separate properly?
This is known as non-disjunction. Non-disjunction can lead to the uneven distribution of chromosomes during cell division, resulting in genetic disorders such as Down syndrome.
What is the name given to a pair of chromosomes that have matching locations for alternate forms of the same gene?
homologous chromosomes

What is the name phase of homologous chromosomes lined up at the equator in pairs?
metaphase I of meiosis
What is the name of the process where pieces of homologous chromosomes are exchanged?
This process is called crossing over.
What is the other name of the reduction division that separates two homologous chromosomes from each other?
Meiosis

What is the other name of homologous recombination?
It's also called "general recombination".Sometimes homologous recombination is mistakenly called "crossover", but crossover is a result of homologous recombination and not really synonymous.
Name the steps in meiosis?
Meiosis consists of two main stages: meiosis I and meiosis II. Meiosis I involves crossing over between homologous chromosomes, followed by separation of homologous chromosomes, resulting in two haploid cells. Then, meiosis II involves separation of sister chromatids, producing a total of four haploid daughter cells.
In meiosiswhat makes up a tetrad?
A tetrad is formed during meiosis when two homologous chromosomes, each consisting of two sister chromatids, align closely together. This results in a structure containing four chromatids, hence the name "tetrad." Tetrads are crucial for the process of crossing over, where genetic material is exchanged between homologous chromosomes, increasing genetic diversity in the resulting gametes. This formation typically occurs during prophase I of meiosis.
