You are studying a species of fly in which females and males each have five pairs of chromosomes. Recombination occurs in males but not in females. How many different egg genotypes (that is, how many genetic combinations) can a single female produce? (1point) How many different sperm genotypes can a single male produce?

-- difference in sexes produced (2:1 ratio female:male) and presence in only females--> sex-linked mutation

-- occurrence of ratio in thirds instead of fourth--> lethal allele

THUS, this is a lethal allele that is lethal in homozygous (female) or hemizygous (male). All of the female must be heterozygous

Explanation:

"do a testcross with a homozygous recessive plant."

and after water is usually warmed by the sun the water temperature raises and then evaporates .
