Courtship Behaviors
What type of courtship behavior includes extravagant movements to attract a mate?
Dancing
What parental behavior includes providing nutrients/or food for their babies?
Feeding Offspring
This tool, invented by Gregor Mendel, is used to predict the probability of offspring inheriting particular traits.
Punnett Square
This plant part protects the developing flower petals before it blooms.
Sepal
Asexual reproduction requires ___ parent(s). Sexual reproduction requires ____ parent(s).
one, two
What is the purpose of courtship behavior?
To attract/find a mate
Which parental behavior includes creating a nest for their babies?
Nest Building
If a homozygous dominant individual (AA) is crossed with a homozygous recessive individual (aa), all offspring will have this genotype.
Aa
This structure connects the stigma to the ovary in a flower.
Style
A seed has hooked barbs on its protective layer. What is the likely method of dispersal?
Animals
What courtship behavior includes having an extraordinary physical appearance?
Colorful dress
Which parental behavior includes educating their babies to survive?
Teaching offspring
A plant with purple flowers (Pp) is crossed with a plant with white flowers (pp). Draw a Punnett square and list the possible flower colors of the offspring.
50% purple (Pp)
50% white (pp).
This part of the plant, located in the flower, produces pollen.
Anther
A seed has fluffy hairs on its protective coating. What is the method of dispersal?
Wind/air
What type of courtship behavior includes making a dwelling that is safe and secure for a mate?
Home Building
What is the benefit of parental behaviors?
Increases the chance of survival for offspring
A tall plant (TT) is crossed with a short plant (tt). Draw a Punnett square and describe the height of all the offspring.
100% tall (Tt).
This slender stalk supports the anther and connects it to the flower.
Filament
A seed is buoyant (floats), what is the method of dispersal?
Water
What is successful reproduction?
Producing offspring that is healthy and adapts to a changing environments.
Are organisms that sexually reproduce or asexually reproduce more likely to demonstrate parental behaviors? Why?
Sexually reproducing organisms: less offspring, more time, need to ensure survival
Is it possible for two white-flowered pea plants (pp x pp) to have a purple-flowered offspring?
No, it’s not possible. Both parents only have the recessive allele (p), so all offspring will be white (pp).
Together, the stigma, style, and ovary make up this female reproductive structure.
Pistil
Why do seeds have protective coating?
To protect them from animals, weather, temperatures, etc.
