Answer:
15
Explanation:
According to linkage theory, two genes present on the same chromosome tend to get inherited together. So the gametes produced are not equal in number and parental type offspring are observed more in number than the new recombinant types.
Here, normal wings, red eyes (420) and vestigial wings, purple eyes (430) are most in number hence they are the parental type offspring.
Vestigial wings, red eyes = 80 : recombinant
Normal wings, purple eyes = 70 : recombinant
Distance between two genes in cM = recombination frequency = (total number of recombinants / total progeny)*100
= [(80+70)/(420+80+70+430)]*100
= (150/1000)*100
= 0.15*100 = 15cM
Answer:The testes contain germ cells that differentiate into mature spermatozoa, supporting cells called Sertoli cells, and testosterone-producing cells called Leydig (interstitial) cells.
