Offspring with a 3:1 ratio suggest that both parent that both parent that give rise to this offspring were both heterozygous. Heterozygous individual is someone who has two different allele at a locus whereby by one gene is dominant over the other gene. example of heterozygous parent is a parent Aa pair of alleles. In this pair gene A is dominant over gene a
Answer:
chloroplast, plant cell, leaf, rose bush
Answer:
1.6896 grams
Explanation:
Given that:
Total pressure = The pressure of
+ partial pressure of 
∴
The pressure of
= Total pressure - partial pressure of 
= (754.8 - 17.55) mmHg
= 737.25 mmHg
At standard conditions:
1 mmHg = 0.00131579 atm
∴
737.25 mmHg will be: (737.25*0.00131579) atm = 0.970065928 atm
P ≅ 0.97 atm
The temperature (T) = 293 K
Volume (V) = 1.31 L
Using ideal gas equation
PV = nRT
0.97 × 1.31 = n × 0.0821 × 293

n = 0.0528
mass of oxygen
= no. of moles * molar mass
= 0.0528 * 32
= 1.6896 grams
Answer:
Your question doesn't make sense. Who is the individual in question?
Explanation:
Red-green color blindness is due to a mutant gene in the X chromosome. An XX female with normal color vision and an XY male with normal color vision have a child with karyotype XXY who is color blind. The likely explanation is that the:_--------.
father was heterozygous for the color-blindness mutation.
mother was heterozygous for the color-blind mutation.
father had CNV of the color-blind mutation.
mother had CNV of the color-blind mutation.
None of the other answer options is correct.
Answer:
mother was heterozygous for the color-blind mutation.
Explanation:
Colorblindness is a recessive disorder. This means that it is expressed only in homozygous genotypes. The responsible gene is present on the X chromosomes. A colorblind female would have the genotype X^cX^c where c is the recessive allele of the gene present on the X chromosome responsible for color blindness. A female with genotype X^cX would have normal visible but would serve as a carrier.
Both the female and the male have normal genotype. Since they had a colorblind child, it means that the female was a heterozygous carrier for the trait and imparted the responsible allele to the child. The male can not serve as a carrier for X linked recessive disorder since they have only one copy of the X chromosome. Therefore, the female was a heterozygous carrier.
