1. 1
Since the ratio is purple flowers to white flowers, and the ratio is 4:1 out of 5 plants, there is 1 white flower. Remember that, in a ratio, the first number is the first one mentioned, and the second number is the second one mentioned.
2. A lizard with a tt genotype with have a short tail
Since the short tail is recessive, it can be represented with a lowercase letter (t), and since the long tail is dominant, it can be represented with a capital letter (T). Because the long tail gene is dominant, if even one capital T is present in a genotype, the lizard will have a long tail. You can label the different kinds of genotypes if it helps.
TT - long tail, since both genes are for a long tail
Tt - long tail, since one gene is for a long tail, and the long tail is dominant
tt - short tail, since both genes are for a short tail
Hope this helps!
Romania, and caper is not the right answer I just need someone to help me answer a question that got taken down 5 times
Answer: Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell.
Explanation:
During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. The chromosomes cross over at points called chiasma. At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.
Answer:
the surrounding ecosystem is nearly or completely destroyed this changes the physical and biological components of the system by killing any biological life and reshaping all structures with magma. this will affect the population by killing anything living haunting life for centuries until new life can start to form such as lichens to break down the hardened rocks nutrients into soil for life
