Answer:
The cell membrane structure is very important because everything alive has cell membranes. The model used to describe the cell membrane is called the <u>fluid mosaic</u> model.
Answer:
Polygenic traits are controlled by a number of separate genes.
Hope it helps! :D
A hypothesis Is when someone thinks of the answer and a theory is when a group of people think of an answer
The diploid number is restored when the two haploid cells combine to create a zygote. Basically when the sperm cell enters the egg cell and makes the offspring.
Answer:
The "short tail" dominant allele is easier to eliminate by selective breeding.
Explanation:
The only way for a recessive allele to be expressed (be visible) is when it appears as recessive homozygotic. These means the organisms need to have 2 copies of the gene. Selective breeding is based on the characteristics that one can see, so if the organism shows the "dilute" phenotype you can keep reproducing this individuals and get rid of the dominant allele.
On the other hand if you have a population with the dominant phenotype, you discard all the ones that have a recessive trait and you breed the dominant phenotype you could still get individuals with the recessive phenotype and individuals that express the dominant phenotype but are heterozygous.
