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:

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
