Cerrena [4.2K]

Answer:

1. The parents genotypes could have been BO and AO

2. wire-hair

Explanation:

There are four possible blood types which are type A, B, AB, O. blood group is the classification of blood based on the presence or the absence of inherited antigenic substances on the surface of the red blood cells. They have hereditary basis and also rely on a series of alternative genes sometimes used in solving dispute of parental heritage. With the four possible blood groups, there are six possible genotypes and these are:

Blood type               possible genotypes

Type A                         AA, AO

Type B                         BB, BO

Type AB                           AB

Type O                              OO

Thus, for parents with blood type B and A to give birth to a child with blood type O, it means their genotype could have been both BO and AO  for them to be able to produce a child with OO. a cross between these two could give rise to OO.

Question 2

Wire hair is dominant (S) to smooth (s), thus wire hair could be in the homozygous (SS) and heterozygous form (Ss) and the smooth hair can only be expressed in the homozygous recessive form (ss).

thus, in a cross between homozygous wire haired and smooth haired, we will have:

homozygous wire haired            homozygous smooth haired

P gen              SS                x               ss

F1 gen.                                Ss

phenotype:                     wire haired

What are nodes, internodes, apical buds, & axillary buds?
xxMikexx [17]
Axillary buds are found at the insertion point of leaves and lateral branches in the nodes and give rise to lateral branches and flowers. Internodes are the stem regions between nodes. They lack lateral organs. It can be said that the stem is made up of nodes, internodes and axillary buds tidily arranged.
