Answer:
Juan father has the sickle cell trait. Gina's maternal grandmother shows the trait and Gina's mother would have inherited it, since she is heterozygous. Gina's paternal grand father shows the trait and Gina's father inherited it as he is also heterozygous.
The chances of Gina to inherit the trait is 25%
(1/2 from both parents)
1/2 + 1/2 = 1/4 equivalent to 25%
Since Gina do not show the trait. A 50% probability for Gina to have it cannot be ruled out since she's not homozygous and there is a 25% probability of being free from the trait.
Take, both Gina and juan to be carriers
HbA HbS x HbAHbS
(Shown in image 1)
We could see a 25% of probability of the trait, 50% chances and 25% of lacking the trait.
Assume Gina is free from the trait and Juan is a the carrier,
HbA HbS x HbAHbA
(Shown in image 2)
The resulting offspring would be at a 50% normal and 50% carriers and none are affected.
My advise for Juan and Gina is to be tested to affirm the likelihood of the trait being present or not as this will allow them plan for giving birth offspring rightly.
Yes i do believe this is right
The consumers are mostly affected secondary consumers.
Please mark me as brainlest.
It because they give us oxygen and without oxygen we would all die from oxygen deprivation.
the process that gives us oxygen is photosynthesis

Answer: Population distributions may be described as <em>random, uniform</em><em> or </em><em>clustered.</em>
Explanation:
In a specified region, a population comprises any number of members of the same species. Populations are described by sizes- the number of individuals; densities- individuals in a set space (per unit area); and distribution- the dispersal or non dispersal of individuals (spread out or clumped). Population distributions may be described in three ways:
- Random: the distribution pattern is haphazard, with no regular spacing; individuals grow independently of each other without competing and resources are consistent. <em>E.g. dandelion seed dispersal by wind </em>
- Uniform: individuals are evenly spaced in a predictable pattern; there may be some interaction and ideally, spaces between them are maximized in order to ensure access to limited nutrients and resources.<em> E.g. human farming- cornfields, orchards; allelopathy in plants like purple sage, which secretes chemicals to prevent the growth of other plants nearby</em>
- Clumped: there is less distance between neighboring organisms and these individuals cluster together. This pattern is most common in environments where resources are scarce, or the species is dependent on social interactions.<em> E.g. lions are highly social and hunt in prides in the wild</em>
