A cross of a red cow (RR) with a white bull (WW) produces all roan offspring (RW). This type of inheritance is known as:
sex-linked
complete dominance
codominance
incomplete dominance
Answer:
Codominance
Explanation:
Both parents carry a dominant trait, so the offspring will have a coat of main colour, and also some hairs of another colour.
These types of cells are found in the reproductive organs and are called
[ germ or somatic ] cells.
Answer:
somatic cells

During meiosis I, how could you have arranged the chromosomes in a different way? How do the differences affect the end result of meiosis??
Explanation:
Meiosis is the formation of reproductive cells, like the egg in the fallopian tube; if not fertilized by sperm, it is expelled by the menstrual cycle.
Some conditions during fertilization can be disrupted by an egg attaching to the fallopian tube instead of the uterus causing an ectopic pregnancy. Arranging chromosomes in a different way causes congenital defects like color blindness, crohn's disease down's syndrome, etc.

How could farmers increase the yields of their crops without using
genetically modified organisms?
Answer:
The reduction of losses by pests, viruses and weeds that compete for soil nutrients, together with savings in phytosanitary products and fuel, indirectly increase the final yield when compared with conventional crops.
Explanation:
also this one, which type of crystal is this?
Answer: Looks similar to a smoky quartz.
can someone please answer these two questions correctly? thank you so much!! ((:
Explanation:
1) 72 of their chromosomes would be somatic and only 2 would be gametes. the number is always two as (normally) an organism will have either 2 X chromosomes (female) or an X and Y chromosome (male).
2) without genetic diversity, an entire species of an organism can go extinct from the same thing as none of them would have mutated any defenses and pass them off to their offspring.
hope this helps :)

Which electromagnetic wave can butterflies,
hedgehogs, and many other animals see?
A. Infrared light
B. Ultraviolet light
C. Microwaves
D. Radio waves
The electromagnetic wave that butterflies, hedgehogs, and many other animals can see is the ultraviolet light that is in Option B, as the ultraviolet light gives these animals a different perspective to visualize.
What role does UV light play in animals?Many animals can see the UV lights, and this is important as the flowers and fruits emit ultraviolet patterns that are invisible to humans but are seen by pollinators such as butterflies and help them find foods.
Hence, the electromagnetic wave that butterflies, hedgehogs, and many other animals can see is the ultraviolet light that is in Option B, as the ultraviolet light gives these animals a different perspective to visualize.

why are metals useful and what are some of their uses?
Answer:
Why are metals useful:
Metals are very useful materials. Metals have many properties, such as strength, toughness, and stiffness. When heated, metals can be shaped into anything from a tiny paperclip to a huge aircraft. They are also good conductors of electricity and heat, which makes them useful for electrics and cooking pans.
What are some of their uses:
As metals are good conductors of electricity, they are used to making wires and parts for equipment and gadgets that function on electrical current.

Raspberries can reproduce by means of runners, which are stems that grow horizontally above the ground. At the region of the runner that touches the ground, a new plant develops. The new plant is genetically identical to the parent because
Answer:
Explanation:
This is because the new cell is produced asexually. Therefore the mutated cells are similar to the parent.
Asexual reproduction refers to the process where a parent plants reproduce or replicate new plants by itself and the new plants carries the same set of chromosomal numbers thereby been genetically identical to the parent.

Select the homologous structures.
a. human arm
b. whale's flipper
c. bird's wing
d. cat's leg
Answer:
Flipper of a whale and bird's wing are homologous structures.
For more better explanation see below.
Explanation:
Flipper of Whale is homologus to the wing of a bird. Homologous organs - The structure which are similar in their morphology, anatomy, genetics and embryology, but dissimilar in their functions.
Flipper of whale and wing of bird has similar morphology and anatomy, but differ in their functions according to their species as well as the habitat where they live in.
A dolphin’s flipper, bird’s wing, cat’s leg, and the human arm are considered homologous structures. Whereas human beings have bones such as the humerus, ulna, radius, wrist bones, and fingers, these features appear as similar bones in form in the other animals. Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.
