Answer:
The possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az
Explanation:
The genotype of F1 progeny is AaZz
The allele pair of gametes would contain one allele for characteristic represented by "A or a" and other allele for characteristic represented by Z or z"
Thus, total four allele pairs will be formed.
First allele pair would be - AZ
Second allele pair would be - Az
Third allele pair would be - aZ
Fourth allele pair would be - az
Hence, the possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az
Answer: her grandpa could not have been the source of either of her XX chromosomes.

<h2>Question:-</h2><h3> Which structure is found in all animal cells?</h3>
<h2>Answer :- Centrioles </h2>
<h2>Explanation:- </h2>
- They are barrel shaped cell organelles only found in animal cell
- There function is to help in division of cell membrane by forming microtubules which help in division of chromosomes ( spindle fibres)
- They play role in arranging microtubules which act as endoskeleton of the cell
- They also help in formation of cell structure like cilia and filaments
When red blood cells are placed in a hypertonic solution, the higher effective osmotic pressure of the bathing solution compared with the intracellular fluid results in water moving down its osmotic gradient and a net movement of water out of the cell via osmosis (10).
