Answer:

Lisa and Monica

Explanation:

<em>The correct answer would be Lisa and Monica.</em>

<u>For X-linked recessive disorders, a female can be unaffected, a carrier, or affected. However, a male can either be affected or unaffected and never a carrier. This is because females have two X chromosomes while males have only one.</u>

In addition, completely filled-in shapes in a pedigree mean that such individuals are affected for the trait in question while half-filled shapes mean the individuals are carriers for the trait.

Hence, individuals in the pedigree that are labeled carriers for red-green color blindness are Lisa and Monica (they both have half-filled shapes).

One oak tree cell with 14 chromosomes undergoes meiosis. How many cells will result from this process,???
Tomtit [17]

Answer:

Four (4) cells

Explanation:

Meiosis is the type of cell division in which four daughter cells that are genetically different is produced. The daughter cells are gametes that have undergone a reduction in their chromosome number (by half).

For example, one cell of an oak tree with 14 chromosomes is said to undergo meiosis. This means that, based on the explanation of meiosis above, the oak cell will give rise to four (4) daughter cells containing 7 chromosomes each.

Jenny is trying to describe a wave. Which example would be the best description?
hoa [83]
<span>I believe the answer would be B - the toy car would hit another toy car that would in turn hit another toy car, and so on. A wave has a ripple effect, so it will continue to happen down the line, until there is a force that stops it, or there are no more cars to hit.</span>

Alternation of generation
Nastasia [14]

Answer:

The answer to this question is given below in this explanation section.

Explanation:

                    "Alternation of generation"

Alternation of generations is the type of life cycle that occurs in those plant  and algae in the archaeologist and the heterokontophyta that have distinct haploid sexual and diploid asexual stages.In these groups a multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes made up of n pairs.A mature sporophyte produces haploid spores by meiosis a process which reduces the number of chromosomes to half from 2n to n.

Two haploid spores germinate and grow into a haploid gametophyte.At maturity ,the gametophyte produces gametes by mitosis which does not alter the number of chromosomes.Two gametes from different organism of the same species fuse to diploid zygote,which develop into a diploid sporophyte . This cycle from gametophyte to sporophyte in the way in which all land plant and many algae undergo sexual reproduction.
