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.

Explanation:

These base pair relationships are often called Chargaff's rules of DNA base pairing, named after the Columbia University scientists who observed that there are equal molar concentration of A & T, as well as G & C in most DNA molecules.

Answer:

Erwin Chargaff

Explanation:

Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal.

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.

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.

Answer:

Human arm and cats leg

Explanation:

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.

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.

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.
