Question

Sexual maturity of the house mouse is attained at the age of
(a) 35 days
(b) 15 days
(c) 45 days
(d) 75 days

Answer 1

Hint: House mouse's sexual maturity is typically reached between five and seven weeks. The day on which they are likely to reach sexual maturity is equal to Bromine's atomic number. The factors for this number include seven and five.

Complete step by step answer:
Mus musculus is marked by immense reproductive capacity. While wild mice may have a reproductive season lasting only from April to September, in this case breeding occurs throughout the year. The estrus cycle lasts 4-6 days, and the estrus cycle lasts less than a day. Postpartum estrus is encountered by females 12-18 hours after giving birth. If conditions are appropriate, females normally have 5-10 litters per year, but as many as 14 have been reported. Gestation takes 19-21 days, but if the female is lactating, it can be prolonged by several days. Litters consist of 3-12 offspring (generally 5 or 6) born naked and blind. After 10 days, they are fully furred, their eyes open at 14 days, they are weaned at 3 weeks, and they reach sexual maturity at 5-7 weeks. It's normally 35 days in a few days. The average lifespan in captivity is around 2 years, but people have lived for as long as 6 years. Most mice do not survive beyond 12-18 months in the wild.
So, the correct answer is ’(a) 35 days’.

Additional information: As a pet or fancy mouse, and as a laboratory mouse, which is one of the most important model organisms in biology and medicine, the house mouse has been domesticated. In 2002, the complete mouse reference genome was sequenced.

Note: A small mammal of the order Rodentia, usually having a pointed snout, large rounded ears, and a long and hairy tail is the house mouse (Mus musculus) . It is one of the most prevalent species of the Mus genus. The house mouse has greatly benefited from associating with human habitation, while a wild species, to the extent where genuinely wild populations are significantly less common than the semi-tame populations near human activity.
