Answer:
Genotype of night blind woman - XnXn
Genotype of normal man - XY
Explanation:
Given
Night blindness (n) is a sex-linked recessive trait. Let us say it is X linked recessive
In this case a man with XY genotype having a diseased X allele will be night blind while a woman will have night blindness if both the X allele are diseased . In case if only one X allele is diseased in women then, she will be a carrier of night blindness defect
Genotype of night blind woman - XnXn
Genotype of normal man - XY

Which step occurs in meiosis to prepare for fertilization in sexually
reproducing organisms?
Answer: 12 sexual reproduction and meiosis concept outline
Explanation: The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell. Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition. Thus, sexually-reproducing organisms alternate between haploid and diploid stages.

Answer:
Genotype, and Phenotype
In a flock of birds, parents can raise small clutches on their own but can increase their clutch size if they have a helper. You want to see if altruistic behavior is likely to spread. To do this you observed a male bird that stayed at his birth nest for a year to help raise the offspring of his father and his stepmother (the original mother died) and then built his own nest the following year. You calculated direct fitness (cost) for the male bird by counting the number of offspring he produced in one year and multiplied it by ½ due to the relatedness between parents and offspring. To calculate his indirect fitness (benefit), you took the total number of offspring produced in his birth nest by his father and stepmother when he assisted them and multiplied it by ½. To determine if this altruistic behavior would spread you subtracted the cost from the benefit to determine whether it was greater than 1. What did you do wrong
Answer:
The mistakes made
Altruistic behavior is measured as ; b - c > 0 and not b - c > 1 relatedness for half siblings = 0.25 and not 1/2Explanation:
The relatedness between ; Mother, father, daughter and son = 0.5 ( 1/2 ) which is included in the direct fitness category ( For the MALE bird )
The relatedness for the Half brother and Half sister of the male bird = 0.25 ( 1/4 ) ( indirect fitness )
hence applying Hamilton's rule
Relatedness = rb - c > 0
where b = benefit , c = cost
∴Total fitness = ∑ direct fitness + ∑ indirect fitness
= 0.5x + 0.25y
hence the mistakes made

C. 9
D. 38
The head makes up the largest percentage of body size __12___ weeks after fertilization.
What is fetal development of head?Fetus brain development is a complex process that continues throughout the pregnancy. At just six weeks, the embryo’s brain and nervous system begin to develop, although the complex parts of the brain continue to grow and develop through the end of pregnancy, with development ending around the age of 25.
At 11 weeks of pregnancy, baby’s head is about half the length of his body. Gradually, the body lengthens out and by about 28 weeks of pregnancy, baby’s body and head look a whole lot closer to normal.
Thus, the best option is B, i.e, 11 weeks among the given alternatives for the question.

A student made a table to show information about the physical structures and organs of birds. The statement which best describes how to correct an error in the table is the ovaries produce the eggs. The correct option is C.
What are the physical structures and organs of birds?Birds are the warm-blooded animals. Their forelimbs are generally modified into wings. They have a well-developed flight muscles which help during the flight of bird. Their hind limbs are adapted for the purpose of walking, hopping, perching, grasping, wading and swimming.
The ovaries produce the eggs. The ovaries are responsible for producing eggs in birds. Therefore, if there is an error in the table that incorrectly identifies the function of the ovaries, it is important to correct it by stating that the ovaries produce the eggs.
Therefore, the correct option is C.

Explanation:
I did it too lol
Purple: FF /White: ff the principles of dominance and segregation to analyze the diagram, alleles would you expect in the F1 plants. Thus, option (a) is correct.
What is segregation?The Segregation Principle defines how pairs of gene variations are divided into reproductive cells. Gregor Mendel discovered the segregation of gene variants, known as alleles, and their accompanying qualities in 1865. During meiosis, allele pairs (different features of the same gene) are separated so that they can pass to distinct gametes.
The diagram was analyzed using the principles of supremacy and segregation. The principle of the impact in segregation was described as Purple: FF / White: ff. This inheritance pattern is known as partial dominance, which means that neither allele is completely dominant over the other: both genotypes can be seen at the same time.
As a result, the Purple: FF /White: ff the principles of dominance and segregation.

Mitosis consists of four basic phases: Prophase, Metaphase, Anaphase, and Telophase. These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. Stages of mitosis: prophase, metaphase, anaphase, telophase.
A. Prophase
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.B. Metaphase
Metaphase is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.C. Anaphase
Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.D. Telophase
Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.The third stage of mitosis, known as metaphase, is when the genetic material that was replicated and carried in the parent cell's nucleus is split into two identical daughter cells.
What are the different phases of mitosis?There are four fundamental stages of mitosis: prophase, metaphase, anaphase, and telophase.
Cytokinesis, which is the process of separating a cell's contents into two new cells, begins in either anaphase or telophase, where the phases are strictly sequentially ordered.
The division of the duplicated genetic material contained in a parent cell's nucleus into two identical daughter cells is called mitosis, and the process begins with the prophase.
