Answer:
1. diploid ,Mitosis
2. mitosis, meiosis
3. diploid, sister chromatids
4. haploid, homologous chromosome
5. haploid, sister chromatids
Explanation:
1. The Giant Panda has 42 chromosomes but these chromosomes exist in the form of homologous pairs therefore the Panda are diploid organisms. The somatic cells of the Panda undergo mitosis like skin cells.
2. The Germ cells are present in the testicles of the Panda which makes an exact copy of themselves by mitosis but these germ cells undergo meiosis to produce sperms.
3. The Mitotic division forms two daughter cells with the same genetic material because the sister chromatids of homologous chromosomes move to the opposite pole.
4. The meiosis I am also known as reductional division as the homologous chromosome separate and move to opposite poles during meiosis I and the ploidy changes from diploid to haploid.
5. During meiosis II, the sister chromatids of a chromosome separate and move to the opposite poles as a result of this the haploid cells are formed.

Explanation:
Answer:
The correct answer would be -
50% heterozygous red flies and 50% recessive brown eyes flies in offspring
Explanation:
This is given that a species of fly has two traits for the eye red eye which is the dominant trait and can be represented by R and the brown eyes trait which is recessive and represented by r.
Given: heterozygous fly which means have both traits gene but as Red is dominant it will have red eyes mates with recessive brown eye fly.
Rr × rr
gametes: R, r and r, r
then,
R r
r Rr rr
r Rr rr
There is 50 % recessive brown eyes flies in offspring and 50% heterozygous red eys offspring.
