How would the karyotype of an organism that reproduces asexualy differ from a human karyotype?
Characteristics. Also, another difference between karyotype and karyogram is that while karyotype describes the number and appearance of chromosomes and includes their length, banding pattern, and centromere position, karyogram contains chromosomes arranged in an appropriate order.Jul
How many homologous pairs of chromosomes does a diploid human cell have?
A human gamete does not have any pairs of homologous chromosomes. A single human gamete contains 23 chromosomes, or a half set. None of these chromosomes are homologous with each other.
Homologous chromosomes is terms of the number of genes and the type of genes they have?
Homologous chromosomes are pairs of chromosomes (one from the female and one from the male), each of which contains genes which correspond to the genes on the other chromosome in the pair. For example, if a chromosome contains a gene for eye color, the corresponding chromosome will also have a gene for eye color in the same place.
What contains genes?
If chromosomes are homologous, that means that each the the four chomosomes that came from the male parent has a corresponding chromosome from the female parent.Prentence Hall Biology
How many pairs of chromosomes are found in a Split Pea cell?
Normal egg cells are haploid and a haploid cell can`t have pair of chromosomes.Pair of chromosomes actually means homologous pairs of chromosomes which are not present in eggs. Human egg contains 23 unpaired chromosomes and Drosophila egg contain 4 unpaired chromosomes which can`t be called 2 pairs as they are not homologous. Some abnormal eggs eg of parthenogenetic animals may possess paired chromosomes.
How many chromosomes does a species have if it contains 10 pairs of homologous chromosomes?
20
What is the total number of chromosomes in a cell that contains chromosomes in homologous pairs?
44
What is a cell that contains both sets of a Homologous chromosomes?
A cell containing both sets of homologous chromosomes is called a diploid. One is usually taken from the mother and one from the father.

What do you call chromosome that look alike and carry genes for the same trait?
Chromosomes that look alike and carry genes for the same trait are called homologous chromosomes. The nucleus contains these chromosomes.
What happens in meiosis during phase 1?
The homologous pairs of chromosomes line up together forming tetrads. During this time, chromatids from the homologous chromosomes cross over and exchange segments so that each chromatid contains both maternal and paternal DNA.

synapsis
What occurs during prophase 1 of meiosis?
In Prophase I: - The duplicated chromatin condenses. Each chromosome consists of two, closely associated sister chromatids. - DNA is exchanged between homologous (similar) chromosomes in a process called 'homologous recombination'. - This often results in the non-sister chromatids crossing over*. The new combinations of DNA created during crossover are a significant source of genetic variation. *at points called chiasmata (plural; singular chiasma).
