Answer:
Part A - Dd
Part B - 50%
Part C - Option E
Part D - dY
Part E - 50%
Part F - 50%
Explanation:
Given,
Let the allele for dominant trait (wild type) be "D" and the allele for recessive ornithine transcarbamylase deficiency (OTD) be "d"
A X-linked recessive gene affects male offspring in a family tree though a female remains a carrier until it mates with a male with the a recessive diseased allele.
Part A
Father's genotype would be Dd. Hence it will pass d gene (X diseased gene ) to her daughter.
Thus , Woman's genotype is Dd
Part B
Genotype of Normal man - DD
DD * Dd
DD, Dd, Dd, DD
One of the two males will have ornithine transcarbamylase deficiency (OTD), an X-linked recessive disorder producing mental deterioration hence, the probability is 50%
Part C
Option E is correct
Only one of the female offspring will have ornithine transcarbamylase deficiency (OTD), an X-linked recessive disorder which will be expressed if other allele is also X linked recessive.
Hence, The chance of being a carrier will be one out of two female offspring i.e 50% and and chance of having OTD is 0%
Part D
dY
Part E
dY * Dd
DY, dY, dD, dd
one out of the two female is diseased. Hence, the probability is 50%
Part F
50%
It's an advantage to both produce sexually and a sexually because by producing sexually, there will be more genetic diversity in the offspring, thus population, and by producing asexually, if there is no potential mates, breeding by oneself can also carry on another generation.
Sexually: Advantage: genetic diversity. Disadvantage: No mate=No offspring.
Asexually: Advantage: No need for the search for a mate/partner. Disadvantage: Basically clones of oneself=No genetic diversity---->leads to high susceptibility to being wiped put by deadly diseases.
Animal cells contain lysosomes, many vacuoles, it is rounded, flagella
Answer:
Four (4)
Explanation:
Two ATP molecules are required to start glycolysis (from glucose), and four are generated by substrate-level phosphorylation. An additional two NADH molecules are generated, which can be used to generate another three to five ATP molecules through the electron transport chain in the mitochondria.
Answer:
The correct answer will be- Uncoupler (ionophore)
Explanation:
Valinomycin is a antibiotic which uncouples the process of ATP synthesis and the electron transport chain.
The valinomycin decreases the yield of ATP synthesis by allowing the inward movement of the K⁺ ions across the inner mitochondrial membrane. This inward movement disrupts the proton gradient which decreases the yield of the ATP synthesis.
Also, the consumption of oxygen increases in the electron transport chain which generates heat during ATP synthesis.
Thus, Uncoupler (ionophore) is the correct answer.
