Answer:
The probability of their first child being colourblind is 1/4
Explanation:
Red-green color blindness is an X-linked recessive disorder.
A woman with normal vision whose father was colorblind has children with a man with normal color vision.
In an X-linked condition, the males only need to get one copy of the affected allele to have the condition and this copy is also inherited by a female offspring.
So in this case, the woman receives the affected recessive allele copy from her dad but since she still has normal vision, she received the normal copy from her mom so she is heterozygote for the trait.
The woman with normal color (XRXr) has a father who is color blind (XrY) has children with a normal man (XRY)
The cross would be
XRXr x XRY
XR Xr
XR XRXR XRXr
Y XRY XrY
Probably of having an affected child is 1/4. Thus, the probability of their first child being colourblind is 1/4
Answer:
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another.
Explanation:
Hare: primary consumer
Wolf: Secondary Consumer
the hare is eating the plants which are producers and is a herbivore but since it still has natural predators it can only be a primary consumer. The wolf on the other hand has no nature predators besides maybe humans so in this ecosystem it is at the top of the web.
Answer:
The organisms in the marine ecosystem converts carbon dioxide to oxygen faster than organisms in other ecosystems.
Explanation:
Simply the organism in the ecosystem seaweed and phytoplanktons makes use of CO2, water, and sunlight to synthesize foods for energy production.During this processes, O2 is liberated as by products from the photolysis of water. These marine photsynthesizers ensures abundant supply of oxygen to the atmosphere.
