Answer:
1. B.
2. B.
3. A.
Explanation:
1. So, the mother does not but the father does carry the gene for polydactyly. Which means that, the offspring was born Pp and, the dominant trait (P) was exposed.
2. A heterozygous trait is one that has both allele forms (in this case, d and D. If both of the parents are Dd, the offspring will also be Dd, and therefore, he has 1/2 chance of being born deaf.
3. Both you and your spouse will be heterozygous (Ee), therefore, since unattached earlobes are dominant
3.1 When two heterozygous traits are bred, you will get the following combinations: yy, Yy, Yy and YY. Which means that your offspring had a 1/4 chance of having attached earlobes, and that is what happened.
3.2 The third option is incorrect, because when you breed 2 homozygous recessive (ee) traits, all of your offspring will be homozygous recessive (ee), which means that the parents would have to be homozygous recessive, but, they cannot since the dominant trait has applied to them.
Answer:
The phenotypic variation for the trait is continuous
Explanation:
Genetically speaking, quantitative traits are controlled by many genes, classes are not easily distinguishable and there is a continuous distribution of the phenotype. These characteristics refer to measurements of quantities (weights, volumes, measurements: kg, m, cm, g, m2, etc.).
In other words, quantitative characteristics are those that exhibit continuous variations and are partly of non-genetic origin; that is, they are greatly affected by the environment.
They both hunt for food and will ruthlessly kill you before you can cry, "MAMA!"
That would be D. Isovolumic contraction
As the name states during ISOvolumic contraction the volume of the ventricles doesn’t change and stays the same so no blood enters or leaves the ventricles. The thing that changes is the pressure of the ventricles that increases.
I can explain the process more if u want in the comments:)
Answer:
Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.
