Heterozygous dominant is the genotype of the sweet pea. thus option A is correct.
What do you mean by genotype?The genetic foundation of a certain trait is called an organism's genotype. While an organism's phenotype refers to its outward appearance.
When an organism has two copies of the same dominant allele, it is said to be homozygous dominant.
The identical recessive allele is present in two copies in a homozygous recessive organism.
An organism is said to be heterozygous if it possesses both the dominant and recessive alleles of a gene.

The graphs below show the changes in crab color at one beach from 1950 to 1990.
The change in crab color is an example of which type of evolution?
O A. Stabilizing selection, because one crab color was preferred over other colors.
O B. Stabilizing selection, because two crab colors were preferred over other colors.
O C. Directional selection, because two extreme colors were preferred over the more moderate color.
O D. Disruptive selection, because two extreme colors were preferred over the more moderate color.
O E. Adaptive radiation, because crabs of a single color evolved to form crabs of several colors.
The change in crab color is an example of Disruptive selection because two extreme colors were preferred over the more moderate color. Thus, the correct option for this question is D.
What is Natural selection?Natural selection may be defined as the selection of a few individuals from any given population according to their favorable variations.
In 1950, the crab color is in the form of stabilizing selection, while in 1990, it changes to disruptive selection that favors the two extreme colors over the intermediate one.
Disruptive selection occurs when environmental conditions changes in two different directions. Due to which variance increases in population.
Therefore, the correct option is D.

HELPPP ASAP!! A population of skunks lives in a woodland habitat. The skunks are unable to leave the habitat because of a large mountain. Describe two reasons this population is not at Hardy-Weinberg Equilibrium.
Some of the conditions are there that must be met for a population or an allele to be in Hardy-Weinberg equilibrium equation are:
1. The population of species must be very large.
2. There must be no migration and population must be isolated in a species.
3. There must be no mutations in a population of species.
4. There must be random mating, which means there are no mating preferences.
So, a population will not be according to Hardy-Weinberg Equilibrium if it is small, or there are , which is not raised, but mutations are expected to occur in future. Skunks can also migrate to another region of a woods despite the presence of a large mountain. As a result of possible mutations and migrations, the population is not in Hardy-Weinberg equilibrium.

Where do sperm go after leaving the epididymis?
OA. Ejaculatory duct
OB. Seminiferous tubules
C. Vas deferens
OD. Urethra
c is the right answer
Explanation:
hope it will helpful for you.
On leaving the epididymis, the sperm is expelled into the vas deference, thus the correct option is option C.
Where is the sperm stored?The sperm are stored in the epididymis. Upon ejaculation, the sperm leaves the epididymis and migrates to the vas deferens.
The vas deferens create a protective fluid that protects the sperm while it's out from the urethra. If sperm does make it into the vagina, there’s a chance that it will fertilize the female egg.
Epididymis is a long tube that functions to transport sperm from the testis to the vas deference. While traveling through the different parts of the epididymis the sperm gets mature and acquires the ability to swim. So epididymis plays an important role in the maturation and transport of sperm.

ok so, I'm having trouble understanding. i believe that the inheritance pattern could be dominant-recessive, but now I'm not too sure. families 1 and 2 have 5 offspring (which doesn't accommodate a dominant-recessive punnett square as that only accounts for 4 offspring). so i tried thinking of it in percentages instead but (in family 1 for example) 2/5 is 40% and 3/5 is 60% so that doesn't work with the dominant-recessive punnett square where each trait is 25%. so either I'm wrong about the inheritance pattern or I'm just full on . someone please help, i don't think I've ever been this confused in bio.
In complete dominance, heter0zyg0us individuals carry both alleles -dominant and recessive- but only express the dominant phentoype. Cross 1: Nn x nn. Cross 2: NN x nn
What is complete dominance?When the dominant allele completely masks the recessive allele, we talk about complete dominance.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
What is a punnett square?The Punnett square is a representation that shows the different types of gamete combinations according to the alleles involved in a cross.
Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.
So, according to the provided data,
Cross 1: gray fur x black fur
F1) 3 gray fur: 2 black fur
Cross 2: gray fur x black furF1) 0 gray fur: 5 black fur
By looking at the phenotype of progeny produced by family 2, and assuming complete dominance, we can infere that black is the dominant phenotype. Why is that? because when you crossed a gray animal with a black animal and the whole progeny is black.
So, assuming a diallelic gene coding for the fur color, we will name
N to the dominant allele that codes for blackn to the recessive allele that codes for gray.Possible genotypes and phenotypes
NN ⇒ Black fur ⇒ dominant phentoypeNn ⇒ Black fur ⇒ dominant phentoypenn ⇒ Grey fur ⇒ recessive phentoypeHere what you need to analyze is which phentoypes appear among the progeny and their frequencies to get to interprete the parents' genotype.
If both parents are h0m0zyg0us dominant (NN x NN), the whole progeny expresses the dominant trait (100% NN)If one parent is h0m0zyg0us dominant and the other one heter0zyg0us (NN x Nn), the whole progeny expresses the dominant trait (50%NN and 50%Nn).If one parent is h0m0zyg0us dominant and the other one h0m0zyg0us recessive (NN x nn), the whole progeny expresses the dominant trait (100% Nn).If both parents are heter0zyg0us (Nn x Nn), the offspring will express both phenotypes in a ratio 3:1 (25% NN + 50% Nn and 25% nn).If one parent is h0m0zyg0us recessive and the other one heter0zyg0us (nn x Nn), the offspring will express both phenotypes in a ratio 1:1 (50% Nn and 50% nn).If both parents are h0m0zyg0us recessive (nn x nn), the whole progeny will express the recessive trait (100% nn).Now let us analyze the crosses,
Cross 1: gray fur x black furF1) 3 gray fur: 2 black fur
You crossed a black animal with a gray animal and the offspring expresses both phenotypes. So the black animal (dominant phenotype) must be heter0zyg0us for coat color.
Parents' phenotype) gray and black
Parentals) nn x Nn
Alleles in Gametes) n n N n
Punnett square) N n
n Nn nn
n Nn nn
F1) Genotype
1/2 = 50% of the progeny is expected to be heter0zyg0us, Nn
1/2 = 50% of the progeny is expected to be h0m0zyg0us recessive nn
Phenotype
1/2 = 50% of the progeny is expected to be black -Nn-
1/2 = 50% of the progeny is expected to be gray -nn-
Cross 2: gray fur x black furF1) 0 gray fur: 5 black fur
You crossed a black animal with a gray animal and the offspring expresses only the dominant phenotypes. So the black animal must be h0m0zyg0us dominant for coat color.
Parents' phenotype) gray and black
Parentals) nn x NN
Alleles in Gametes) n n N N
Punnett square) N N
