Gametes produced without crossing over are genetically identical to the parent cell, whereas gametes produced with crossing over have a mix of genetic material from both parents due to exchange of genetic material between homologous chromosomes. Crossing over increases genetic diversity in offspring.
During crossing over in meiosis, four genetically distinct gametes are produced.
In the absence of crossing over during meiosis, four genetically distinct gametes are produced.
Four different genetic types of gametes would be produced without crossing over. These would be AB, ab, Ab, and aB.
If crossing over does not occur during meiosis, two genetically distinct gametes are produced.
The father must have contributed an X chromosome if a normal female is produced.
The father must have contributed an X chromosome if a normal female is produced.
The chromosome number of a tapeworm produced by budding is diploid. This means that the tapeworm has two sets of chromosomes in its cells.
