Answer:
All of their sons would be colour blind
Explanation:
Given that colour blindness is X linked recessive condition which means that the gene is located on X chromosome and when present in recessive homozygous condition, it will be expressed. Hence if XC is dominant allele and Xc is recessive allele, XcY and XcXc will be colourblind.
The male has normal vision and males have only one X chromosome so his genotype is XCY.
The female is colourblind and females have two X chromosomes so her genotype is XcXc.
Their children:
XC Y
Xc XCXc XcY
Xc XCXc XcY
All the sons have XcY genotype where gene for colourblindness is in recessive condition hence all of their sons would be colourblind.
Answer:
A. simple
Explanation:
Asexual reproduction is mainly used by bacteria or small organisms that are too simple to have created a mechanism for sexual reproduction. The advantage of sexual reproduction is the recombination--why do you think you're not an exact copy of your parent? That's because they didn't have you via asexual reproduction.
Why not B: This is the opposite.
Why not C: This isn't necessarily a requisite condition; many bacteria do not live underwater.
Why not D: This is certainly wrong. Bacteria are not extinct, and not looking to be so anytime soon.
Answer: C. Temperate forests
Temperate forests contains the most biodiversity of deciduous tree species. These deciduous trees shed their leaves once in a year. The temperate forests are found in the Northern Hemisphere, North America, East Asia and Central and Western regions of Europe. The deciduous trees have broad leaves. Appalachian oak, hemlock, maple and pine are some of the deciduous trees species found in temperate forests.
