The answer would be: <span>A.50%
A child will get genetic material from both parents, half from the father and half from the mother. This is why the gamete cells (sperm/ovum) are made from meiosis and only have 50% of the original genetic material.
</span><span>In this case, the parent carries a deletion on one of the two homologous chromosomes. Since the gamete only has one of the chromosomes, half of the gamete of this parent would have the defective chromosome and the other half have a normal chromosome. So, the chance for the child to inherit the defective gene is 50%.</span>
Answer:
Smooth & yellow: 9
smooth & green: 3
wrinkled & yellow: 3
wrinkled & green: 1
Explanation:
Gene controlling seed color are yellow Vs green
Gene controlling seed texture are smooth Vs wrinkled
In F1 generation, A true breeding smooth green plant (SSyy) is crossed to a true breeding wrinkled yellow (ssYY)
Off spring in F1 generation are smooth yellow (SsYy)
This means smooth texture is dominant over wrinkled texture and yellow color is dominant over green
in F2 generation, the cross is carried between SsYy
SY Sy sY sy
SY SSYY SSYy SsYY SsYy
Sy SSYy SSyy SsYy Ssyy
sY SsYY SsYy ssYY ssYy
sy SsYy Ssyy ssYy ssyy
Smooth & yellow: 9
smooth & green: 3
wrinkled & yellow: 3
wrinkled & green: 1
