Summary Introduction
To review:
The given blank space in the statement, “in mammals, males have _____ sex chromosome and females have ______ sex chromosomes. The sex of offspring depends on which chromosome is present in the ______.”
Introduction:
Eukaryotes are the multicellular organisms. These undergo meiotic cell division for the production of reproductively active cells known as gametes. These gametes are different for a different individual depending on their sexual orientation. Females produce ovum while males produce sperms. Human possess fixed number of chromosome and the arrangement of the chromosome for the purpose of study and analysis is known as karyotyping.
