Answer:
X linked inheritance is one of the mechanisms of the inheritance which is associated with the mutation of the gene present on the X chromosome.
The characteristics of the X linked recessive inheritance that must be observed in the pedigree analysis will be-
1. X linked trait is always passed from the mother to the sons (females to males)
2. The males (XY) are usually affected by the gene as only one copy of the recessive gene in males can show its effect.
3. Females are the carrier of the disease but they are not affected by the condition.
Answer: In Meiosis,chromosomes in a diploid cell resegregate, to give four haploid cells. Genetic diversity takes place during this early step of meiosis. DNA replication takes place before Early Meiosis commence. Pairing of homologous chromosomes which forms synapses is unique to Meiosis.
Explanation: Meiosis is a type of cell division which aides the formation of reproductive materials like the GAMETES SUCH AS SPERM CELLS AND EGGS,During Meiosis cell division takes place which reduces the number of chromosomes in the parent cell by half and produces four daughter cells, Meiosis is essential to guarantee genetic diversity in living organisms.
