Sex determination is primarily governed by either the male heterogamety of XX/XY type or female heterogamety of ZW/ZZ type with a seemingly one-to-one sex ratio of males to females. Many breeders of mammals would prefer a bias though towards a greater proportion of females to males due to males being overall less productive to females. What benefit is there is having a relatively equal proportion of male to female offspring when, in production terms, this is less then desirable?

Given the results of our calculations of inclusive fitness for male pied kingfishers (Ceryle rudis) (see Table 13.1), isn’t it maladaptive to be a delayer? Why aren’t there any completely sterile helper male pied kingfishers? Please don't write from any online source.
The genetic identity of the female parent is RrGg and the genetic identity of the male parent is Rrgg. They produce 320 offspring together from a single mating: 57 red-eyed females with grey bodies, 61 red-eyed females with yellow bodies, 22 brown-eyed females with grey bodies, 20 brown-eyed females with yellow bodies.59 red-eyed males with grey bodies, 63 red-eyed males with yellow bodies, 20 brown-eyedmales with grey bodies, 18 brown-eyed males with yellow bodies. Show the simultaneous transmission of the two genes involved to give rise to the progeny given with the use of genetic diagrams and summaries as required. (Hint: you are only requiredto show the simultaneous transmission from the P to F1 generations)
In reptiles, sex determination was thought to be controlled by sex-chromosome systems or by temperature-dependent sex determination without an inherited component to sex. But as we discussed in section 7.6, in the Australian lizard, Pogona vitticeps, it was recently revealed that sex is determined by both chromosome composition and by the temperature at which eggs are incubated. What effects might climate change have on temperature- dependent sex determination in this species, and how might this impact the sex ratio for this species in subsequent generations?
Minotaur is only found in the Labyrinth on the island of Crete. The area is famous for its annual spectacle of "Minotaur run," where herds of Minotaur rush out of the Labyrinth to reach their breeding grounds on the beautiful Aegean seashore. A group of Olympian scientists discovered that the horn size of the Minotaur is controlled by a single locus, with HH individuals having the longest, the Hh the medium, and hh the shortest horns. It is further found that the long-horned individuals tend to be tangled up along the way during the annual migration out of the Labyrinth, such that only 80% of the HH individuals can make it out of the Labyrinth alive. Once outside the Labyrinth, the short-horned individuals tend to be less successful at finding food, thus 60% would die from starvation before the beginning of the breeding season. Since the Hh individualsâ horn size are just right, so all of them survive the annual challenge. Initially, the annual migration of Minotaur started out with…

The achoo syndrome (sneezing in response to bright light) and trembling chin (triggered by anxiety) are both dominant traits in humans. A. What is the probability that the first child of parents heterozygous for both the achoo gene and trembling chin will have achoo syndrome but lack trembling chin? B. If the same couple decides to have five children what is the probability that at most three will have achoo syndrome? C. If the same couple decides to have five children what is the probability that at most three will have achoo syndrome?
The achoo syndrome (sneezing in response to bright light) and trembling chin (triggered by anxiety) are both dominant traits in humans. What is the probability that the first child of parents who are heterozygous for both the achoo gene and trembling chin will have achoo syndrome but lack the trembling chin? What is the probability that the first child will have neither achoo syndrome nor trembling chin?
Suppose Jonathan breeds flowers and wants to optimize production of offspring with both short stems and white flowers, which are coded for by two genes with the recessive alleles t and p, respectively. In flowers, T codes for tall stems and P codes for purple flowers. Jonathan crosses two heterozygotes that produce 544544 offspring. How many of these 544544 offspring are predicted to have both short stems and white flowers? please help solve and please explain thank you

A red-eyed (dominant) female with a grey (dominant) body is crossed with red-eyed (dominant) male with a yellow body (recessive) The pair of fruit flies (given above) produce 320 offspring together from a single mating: 57 red-eyed females with grey bodies, 61 red-eyed females with yellow bodies, 22 brown- eyed females with grey bodies, 20 brown-eyed females with yellow bodies. 59 red-eyed males with grey bodies, 63 red-eyed males with yellow bodies, 20 brown-eyed males with grey bodies, 18 brown-eyed males with yellow bodies. From this information only (NO genetic diagrams required), what evidence and logic can you use to deduce the genetic identity of the parent flies?
