Why does the fungus: Phytophthora infestans, attack potato crops?

Phytophthora infestans is an oomycete or water mold, a fungus-like microorganism that causes the serious potato and tomato disease known as late blight or potato blight. Early blight, caused by Alternaria solani, is also often called "potato blight".

Explanation:

Explanation:

Late Blight is caused by the fungus Phytophthora infestans. The late blight fungus is especially adapted for growth under conditions where water is present and cool temperatures persist. Temperatures ranging from approximately 50 to mid 90s oF will enable disease progression in the field (Franc et al., 1996).

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
