What characteristic of male Australian Lyre birds and Mockingbirds increases their chances of mating?
CHARACTERISTICS OF THEIR CHANCES OF MATING-
AUSTRALIAN LYRE BIRD- 1. Wild male lyre bird often elect to match subsets of songs from their extensive vocal repertoire with different combinations of tail , wing, leg movements predectible gestures to engage in intentional choreography.
2. Females might exercise mate choice by discriminating among males on the basis of integrated performance co-ordination.
3. Lyrebirds are famous for their accurate mimic sounds . They can mimic almost 20 types of bird's call.
4. During breeding period males perch atop display mounds in their territories and perform for females in a prelude to mating .
5. Shivering this curtain of feathers theatrically over their heads ,Flapping their wings , hopping and stepping from side to side .
MOCKING BIRDS-
1. Male and female both reach their maturity after one year of life and the male arrive before the beginning of the season to establish their territories.
2. The males use a series of courtship displays to attract the females to their sites.
3. They run around the area either to showcase their territory to the females .
4. Males also engage themselves in flight to showcase their wings.
5. They sing and mimic to attract female. The species remain monogamous for many year.
What characteristic of male Australian Lyre birds and Mockingbirds increases their chances of mating?
Birds of paradise are beautiful birds often with spectacularly long tails. The male birds will often dance in open spaces known as a lek to attract females. A researcher watched the displays correlated the length of the male birds tails to successful mating. 1. What is the dependent variable in the experiment? 2. What is the independent variable in this experiment? 3. What is a reasonable alternate hypothesis for his experiment? 4. What is a reasonable Null hypothesis?
• A small male will do better mating at sea when suitable beaches are rare and successfully defended by large males. A small male will do better mating at sea when suitable beaches are more common than are large, dominant males. Q4.16. Under what conditions would a female be expected to improve her fitness by mating with a small male at sea rather than with a large male defending a harem on shore? She would do better mating with a...
What is an important difference between chromosomal sex determination in birds and mammals? A. Female birds have two different sex chromosomes while female mammals have two different sex chromosomess. B. The heterogametic sex in birds is male while the heterogametic sex in mammales is female. C. The homogametic sex in birds is female while the homogametic sex in mammals is male. D. The heterogametic sex in birds is female, while the heterogametic sex in mammals is male.
You know that overall there is a 60% chance to observe birds engaging in a specific mating dance. You want to study this dance, so you need to know how many birds to observe to have a good chance to see it. How many birds would you need to observe to have a 95% chance of observing the dance? Let’s say your previous research has also shown that the same species in Florida dances for 8 minutes on average, with...
Assortative mating: Assortative mating is a nonrandom mating pattern where individuals with similar genotypes and/or phenotypes mate with one another more frequently than what would be expected under a random mating pattern. Researchers studying this topic collected data on eye colors of 205 Scandinavian men and their female partners. The table below summarizes the results (rows represent male eye color while columns represent female eye color). For simplicity, we only include heterosexual relationships in this exercise. (please round any numerical...

The increase in singing that male birds exhibit in the spring seems to be prompted by an increase in their testosterone levels. (6 marks total) a) Are testosterone levels a proximate or ultimate cause of singing? Explain. (3 marks) Note: do (b) or (c), as appropriate. b) If they are not a proximate cause, what is? Explain. (3 marks) c) If they are not an ultimate cause, what is? Explain. (3 marks)
In birds, the male is the homogametic sex. Females are ZW. A dominant sex-linked allele, ZS gives silver feather color. Zs gives gold. Mate a silver female with a gold male. How can you identify male and female offspring by feather color alone?
A wildtype female fly ends up mating with a male carrying a Y-linked allele that causes antennapedia. If their F1 progeny cross, what will be the expected ratio of F2 antennapedia flies to wildtype? Would it be 100% or 50% or neither something like 25% or 0%?
The exaggerated plumage and colors of male birds is thought to result from to different theories: runaway selection and the handicap principal. Using an example, explain the difference between these two theories.
