Gametes form in a cell division process called meiosis, in which a cell splits into four copies instead of the usual two so that the gametes contain half the normal number of chromosomes-just one of each of the
A genome is packaged into pieces of DNA called chromosomes. Chromosomes condense during cell-reproduction and are passed down from parent to offspring. Humans possess 23 pairs of chromosomes. The first 22 pairs are called autosomes...
The difference between diploid and haploid cells is that diploids contain two complete sets of chromosomes and haploids contain only one set of chromosomes. Haploid cells are produced when a parent cell divides twice, resulting in two diploid cells with the full set of genetic material upon the ...
Humans are diploid, meaning they have two copies of each of the 23 different types of chromosomes found in humankind. This means that each human has 46 chromosomes in total, half of which come from each of their parents. Some people can have more or less chromosomes. For example...
In normal meiosis, chromosomes first duplicate, resulting in pairs of sister chromatids. This round of replication is followed by two rounds of division, known as meiosis I and meiosis II. During meiosis I homologous chromosomes recombine and are separated into two cells, each of them comprising...
Generally, the two main factors considered to underlie the production of unreduced gametes are hybridi- zation and environmental factors. Hybrids derived from distant hybridization (hybridization between species or higher-ranking taxa) combine two sets of chromosomes from different taxa. In meiosis, ...

In sexual reproduction, the gamete cells contain how many chromosomes? Which of the following choices represents the genotype of an individual diploid organism? a. BCd b. bcd c. BbCd d. BbCCdd A diploid cell contains [{Blank}...

For each 23 pairs of chromosomes, the haploid egg cell will have either a maternal or paternal chromosome, but it can be different for each pair. This explains how the process of meiosis contributes to genetic ___. Choose the correct answer...
