Answer:
The model showing the condition must represent a recombination between the X and Y chromosome during meiosis in male.
Explanation:
In males, the sex chromosomes are X and Y, whereas, the females have XX chromosomes. When the X chromosome of males fuses with the female gamete it give rise to a female progeny.
The Sry gene is present on the Y chromosome. In some cases, the recombination between the X and Y chromosome during meiosis in males takes place and result in an X chromosome containing Sry gene. This Sry gene is responsible for the male characters and progeny carrying two X chromosomes, in which one has the Sry gene would have the male characters.
So, the in this case should represented the crossing over between the X and Y chromosomes in males and then passing of the Sry containing X chromosome to progeny.
Answer:
A double helix shape of DNA
Explanation:
Answer: Chlorophyll
Explanation:
Chlorophyll is the photosynthetic pigment found in the chloroplasts of green plants. It helps the plants to trap solar energy radiated from the sun during day light. This energy trapping by chlorophyll occurs during the Light-dependent stage (first stage) of photosynthesis, followed by Light-independent stage (second stage)
