Explanation:
4 dominant allele because all pea plant present in TALL condition , not a recessive allele is presents
These genes could have arisen by gene duplication.
<h3>What is gene duplication?</h3>
Gene duplication is the process of copying a section of DNA that codes for a gene. A retro transposition event or a recombination mistake are both potential causes of gene duplication. As a result, the duplicate gene coding may experience a significant number of modifications throughout time. This might prevent the gene from functioning or, in other situations, give the creature a benefit.
Gene duplication is a phenomenon that can happen through a variety of ways:
- Ectopic Recombination: Uneven crossing-over between misaligned homologous chromosomes during meiosis might result in duplications. A duplication at the exchange site and a reciprocal deletion are the results of this recombination.
- Replication Slippage: Short genomic sequences can be duplicated as a result of the replication error known as replication slippage. DNA polymerase starts copying the DNA during replication, but eventually the polymerase separates from the DNA, causing replication to stall. The replicating strand is incorrectly aligned when the polymerase reattaches to the DNA strand, which accidentally results in several copies of the same portion.
- Aneuploidy: When a single chromosome's nondisjunction causes an abnormally high number of chromosomes, this condition is known as aneuploidy. Aneuploidy is frequently damaging and frequently causes spontaneous miscarriages in mammals. Some aneuploid people can survive. For instance, human trisomy 21 causes Down syndrome but is not lethal.

Can spread themselves more easily and reproduce more while not staying in the same spot.
Answer:
A. Estradiol
Explanation:
Estradiol, which is also referred to as 17 beta-estradiol, is an estrogen steroid hormone. This form of estrogen is one of the major female sex hormone that plays major role in the female reproductive system such as regulation of the estrous and menstrual cycle. It also helps in regulating body metabolism.
Reduction in the level of Estradiol is one of the problems common in women approaching menopause. Optimal level of estradiol in the body helps improve fertility in the body as symptoms such as such as vaginal dryness, burning, itching that are associated with menopause are reduced to the barest minimum.
The supplement taken by Priya in order to thin the mucus and allow sperm to get through the mucus to the uterus most likely works to benefit the body by increasing <em>estradiol.</em>
