</span>
3. Metaphase I. <span>Meiosis prophase I is the phase in which chromosomal crossing over occurs. The phase after prophase I is metaphase I.

4. </span>Its body cells would have 36 chromosomes, and its gametes would have 18 chromosomes. <span>In the gametes, there are half of the number of chromosomes present in the body cell.

5. </span><span>A species has to adjust rapidly to a changing environment. To adjust to the environment, crossing over is necessary, and it does not occur in mitosis, but meiosis.

6. 50 percent. 
Parents:          Yy      x     yy
Offspring:    Yy    Yy    yy   yy
50 % is Yy  and 50% is yy.

7. </span><span>One parent had white eyes and the other was heterozygous for eye color. The ratio in the offspring is 50-50. The only possibility is the following:
Parents:       Rr     x     rr
Offspring   Rr    Rr   Rr   Rr

8. </span><span>Their fur will be a mixture of red and white hairs. The offspring will be heterozygous. They will have alleles for both red and white hairs and both will be expressed.
</span>
9. Not enough information.

10. <span>Both of the parents' genotype must have been Pp. The genotype of the white plant is pp since it is recessive:
Parents:        Pp     x     Pp
Offspring:   PP   Pp   Pp   pp
One of the four is white.</span>

This table shows 3 different groups of crocodiles. Each group, A,B and C, is in a category based on their total lengths in meter
nirvana33 [79]

Since the main food source for the crocodiles from the group B is fish, overharvesting of fish will have a negative impact on Group B.

Overharvesting of fish or overfishing can usually have serious consequences on aquatic ecosystems, including organisms such as crocodile in this example. Overfishing results not only in affecting the balance of life in the oceans, but also of the coastal communities who depend on fish for their way of life.
