Answer:
cc × cc
Explanation:
This question involves a single gene coding for plant seedling. The green allele (C) is dominant over the white allele (c). This means that the green allele will mask the phenotypic expression of the white allele in a heterozygous state (Cc).
In this experiment where plate 1 only contained white seedlings instead of all green, this illustrates that all the offsprings were recessive. This is because the parental genotypes were both recessive for the color trait i.e. cc.
Note that, the recessive trait can only be expressed when the recessive alleles are present in a gene. Therefore, the parental genotype would have been cc × cc, in order to give rise to all offsprings with the recessive trait (white colour).
Each of a Number of small areas of habitat, typically of one square meter, selected at random to act as samples for assessing the local distribution of plants or animals.
Answer:
Explanation:
The thoracic cavity is the anterior ventral body cavity found within the rib cage in the torso. It houses the primary organs of the cardiovascular and respiratory systems, such as the heart and lungs, but also includes organs from other systems, such as the esophagus and the thymus gland.
Answer:
The first line of defence (or outside defence system) includes physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, 'friendly' bacteria and white blood cells called neutrophils.
Explanation: brainlieast...?
The answer is (B) Edward's Syndrome, Down Syndrome, Klinefelter's Syndrome.
These syndromes are caused when there is an extra copy of chromosomes present in the cells.
In Edward's syndrome, there is an extra copy of the chromosome 18.
In Down's syndrome, there is an extra copy of chromosome 21.
In Klinefelter's syndrome, there is an extra copy of X chromosome.
