Answer:
1/4
Explanation:
In order for a plant to be short and yellow, it needs to have hοmοzygous lowercase letters for height and color.
If the plant had one capital letter for either height, color, or both, this would dominate the recessive gene and would not allow the plant to exhibit the recessive trait.
The short, yellow plant has a genotype of:
ttggThe plant that is heterozygous for both traits means that its genotype has both the dominant (capital) and recessive (lowercase) letters.
The heterozygous plant has a genotype of:
TtGgWe can use a dihybrid crossing of alleles in a 4x4 Punnett square. To figure out which four pairs of alleles to use for crossing, we can FOIL the genotypes of the two plants getting crossed.
(tt) · (gg) = tg + tg + tg + tg (Tt) · (Gg) = TG + Tg + tG + tgUse these pairs of alleles to cross in the Punnett square. To see which offspring will be short and green, we need to look at the pairs of alleles for the height and color traits separately.
Short plants must have the genotype of tt.
Green plants can have the genotype of GG or Gg.
Look at the Punnett square to see which genotypes are hοmοzygous for the short trait and either hοmοzygous or heterozygous for the green trait.
We can see that the third row of genotypes consist of ttGg, which corresponds to the short and green phenotypes.
Therefore, 1/4 of the offspring will be short and green.

Please answer quickly!There are _____ pair(s) of autosomes and _____ pair(s) of sex chromosomes in a human somatic cell.
A. 2;44
B. 1:22
C. 44;2
D. 22;1
Answer:
D. 22;1
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
The human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.
Hence, there are 22 pairs of autosomes and 1 pair of sex chromosomes in a human somatic cell.

Children inherit half of their genes from parents. Explain Why?
Answer:
This is because the two parents share one or more common ancestors and so carry some of the same genetic material. If both partners carry the same inherited gene change, their children are more likely to have a genetic condition.
Answer:
yes
Explanation:
The chromosomes in cells line up in pairs and exchange bits of genetic material before forming an egg or sperm cell. Each mature egg and sperm then has its own specific combination of genes, which means children will inherit a slightly different set of DNA from each parent.

Are genetic mutations avoidable? Explain.
Answer:
Mutations happen in our cells all the time. It's actually how all humans grow and change. The vast majority of mutations are harmless. Thus, they aren't avoidable.
Mutations occur in our cells all the time. It's how all humans grow and transform. The vast bulk of mutations is harmless. Therefore, they aren't avoidable.

Which structure fuses to form a diploid zygote during sexual reproduction?
The top red box is the structure that fuses to form a diploid zygote during sexual reproduction. This top structure is usually the cap that contains numerous spores.
What is Zygote?Zygote may be defined as the outcome of successful fertilization between male and female gametes. It is diploid in nature.
The spores of such cap structure contain a nuclear pair that is responsible for the formation of the diploid nucleus and thus the resultant zygote.
The bottom red box illustrates hyphae, and the middle boxes represent the ring and stem portion respectively.
Therefore, the top red box is the structure that fuses to form a diploid zygote during sexual reproduction. This top structure is usually the cap that contains numerous spores.

Answer:
A.Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein
Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein.
What is Replication?
A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
The ability of each DNA strand to function as a template for duplication is essential to the replication process. DNA double helix unwinding occurs at specified locations, known as origins, where DNA replication begins.
The production of a primer, a brief section of RNA that serves as the beginning point for the synthesis of fresh DNA, follows. The DNA is then replicated by a protein called DNA polymerase by matching bases to the original strand.
Therefore, Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein.

Enlist the features of cell membrane.
Answer:
It is the outermost covering of a cell that separates the contents of the cell from its external environment.
It only allows the entry and exit of some materials. It also prevents the movement of some. Therefore, it is also called a selectively permeable membrane.
Some substances like carbon dioxide and oxygen can move across the cell membrane due to the process known as diffusion.
Water also obeys the laws of diffusion. The movement of water molecules through a selectively permeable membrane is called osmosis.

The energy of the reactant is lower and the energy of the product is higher in this kind of reaction, it is called an endothermic reaction.
What is an endothermic reaction?A thermodynamic process in which energy is absorbed is called an endothermic reaction. In this kind of reaction, when heat is given during the reaction, is absorbed by the reactant to form the product. It takes heat from its surrounding.
Some examples of endothermic reactions are:
The melting of ice to form water is an endothermic reaction.When nitrogen and oxygen react with each other to form nitric oxide, it absorbs energy.When ammonium chloride (NH₄Cl) reacts with water (H₂O), it absorbs heat.Hence, the correct sequence is:
