A. multiply the chance that it will be a boy x the chance he will have PKU (1/2 x 1/4)
<span>B. chance of having PKU + chance of albinism </span>
<span>C. chance PKU x chance albinism</span>
Answer:
B
Explanation:
The only difference between the speed and the velocity is that the velocity tell us about magnitude and direction but speed tell us about magnitude only. Hence, the correct option is,
Answer:
The right answer to this question is option A) island forms and mainland forms descended from common ancestors.
It's known in science that a long time ago, all the continents were only one, united all together in a bigger one. This can be observed by the way every continent can fit another one.
A proof of that too, is evolution, when we find organisms in an island that share some characteristics with organisms from another island, that can mean some things, they come from the same place, or these islands share characteristics that lead these organisms to be this way through evolution.
The basics would be that you'd need to find out if they could exchange genetic information. If not, they couldn't be considered part of one species. Set-up 2 artificial environments so both groups would produce pollen at the same time. Fertilise both plants with the other's pollen. Then fertilise the plants with pollen from their own group.
Count the number of offspring each plant produces.
If the plants which were fertilised by the opposite group produce offspring, they are of the same species. You can then take this further if they are of the same species by analysing if there is any difference between the number (and health) of offspring produced by the crossed progeny and by the pure progeny. You'd have to take into account that some of them would want to grow at different times, so a study of the progeny from their first sprout until death (whilst emulating the seasons in your ideal controlled environment). Their success could then be compared to that of the pure-bred individuals.
Make sure to repeat this a few times, or have a number of plants to make sure your results are accurate.
Or if you couldn't do the controlled environment thing, just keep some pollen one year and use it to fertilise the other group.
I'd also put a hypothesis in there somewhere too.
The independent variable would be the number of plants pollinated. The dependant variable would be the number of progeny (offspring) produced.
The answer is alleles detached from one another during
anaphase of meiosis I, when the homologous pairs of chromosomes separate. During
anaphase I, homologous pairs are drawn apart, and
they go in the direction of the opposites of the cell. Meiosis I finishes
with the manufacture of two haploid daughter cells for the reason that
the homologous pairs of chromosomes have been separated.
