A challenge to traditional (pre-1860) ideas about species came from embryology, when it was discovered that embryos of dissimilar organisms, such as sharks and humans, resemble each other. Embryology involves the study of the formation and the development of an embryo and the fetus. It is one type of evidence of evolution such that the embryos of many different kinds of animals, mammals, reptiles, birds, fish among others, are similar showing a common ancestry.
Answer: Yes
Explanation:
Carrying capacity can be defined as the total number of members of the population of a species that an ecosystem can sustain in terms of providing resources in the form of food, shelter and others. When the resources are available in surplus then the population of a species increases exponentially but declines when resources become scarce. The human population is increasing tremendously all over the world this is supported by the resources like food, water, fossil fuels, air, minerals, and others. But some of these resources are decreasing due to overuse and may not be available in future to sustain the future generation.

Answer:
It concludes that the man is not the real father of the girl child.
Explanation:
Sex-linked or the X linked characters are the traits that inherited in a change or mutation in X chromosomes that cause the phenotype change in the male, which are homozygous for the gene as only possess one X chromosome and one Y chromosome, and Females if they are homozygous for the gene.
In the question, Man has a normal color vision (XrY) that means he has no mutated allele of color blindness. female has color blindness so that means she is a homozygous chromosome for the gene. Cross between these two results in 50% carrier daughters (XrXR) and 50% color blindness son (XRY). It means there is no chance for the color blind daughter.
Thus, the correct answer would be the man is not the real father of the girl child.
