Answer:
100%
Explanation:
A sex-linked trait is a trait which is inherited on the sex chromosomes (X and Y chromosomes). This means that that trait is only inherited by offsprings of a particular sex. In this question, a family is said to have a Y-linked disease that affects the father.
Note that, Y chromosomes are only present in the male sex, meaning that a father will always transfer its Y chromosome to all his male offsprings. Since this disease (trait) is on the Y chromosome, it means that all male offsprings i.e. 100% of this father will have the disease.
Answer:
150 individuals
Explanation:
If the dark phenotype is determined by a dominant allele at a single locus, the ratio of dark green phenotype to pale green phenotype at F2 should be 3:1 according to the Mendelian standard.
200 to 3:1 = 150:50
<u>Hence, if 200 F2 individuals were characterized, one would expect the number of dark green individuals to be 150 while the pale green would be expected to be 50.</u>
Answer: option c and d is right
Explanation:
This distinct features can be seen on venus, Saturn but all planets have it's signatory color as seen by astronomers.
<h2>Endothermic Process</h2>
Explanation:
An example of endothermic process is :
Heat is needed for water to boil.
Endothermic process can be defined as a process in which heat energy is absorbed from the surrounding that bring about changes in the molecular level like breaking chemical bonds, inter-molecular force of attraction etc.
Boiling of water is an endothermic process because during this process water absorbs heat , its kinetic energy increases and then it boils.
Yes, it is possible.
In this case both of the parental plants were heterozygotes and they manifested dominant allele in their phenotype, which is round seed.
P: Aa x Aa
F5: AA, Aa, aA, aa - possible genotypes in fifth generations.
A- dominant allele (round seeds); a- recessive allele (wrinkled seeds)
Wrinkled phenotype is manifested only if there are two recessive alleles present.
